Great quality and value for money
Great value for money. Nice looking and reasonably sturdy shed. Very happy. Assembly took a full day, quite fiddly. Especially difficult in gusty conditions and required a few sets of hands until all of the walls were erected. The shed needs to be square otherwise especially when you get to the roof you’ll notice quite a bit of misalignment. We had to twist the shed around and do some minor adjusting and then things fell into place though. Scratches easily, would have been nice to have got a tiny bit of touch up paint alongside.

Very pleased indeed!
Having spent weeks researching which shed would best suit my needs, it became apparent that the majority of retailers sell one of two makes of shed - both of which had significant flaws identified by buyers. On discovering an alternative - the Duramax brand - the reviews were much more favourable. Coupled with the immediate availability and excellent service of Amazon, I decided to give it a go. What a pleasant surprise awaited! The shed was delivered within a couple of days, rather than the many weeks you'd expect from other sellers. So far, so good! On unboxing, the components were well packaged. The instruction booklet was clearly illustrated and highly comprehensive. Each component in the box was numbered for ease of identification. Even the instructions for constructing a base were highly detailed! Although most of the job of putting it together could be done by one person, there were certain aspects that definitely needed two people, so make sure you've got someone to give you a hand. Once built (a job that took a couple of days), it looked fantastic! I'm very, very happy with the quality, price and ease of build, and although it's not yet been tested for its weatherproofing, there's no obvious reason to doubt it. I am a genuinely satisfied customer!

Value for money and sturdy when finished. I had to modify a bit for weatherproofing the top though.
I've got myself a waterproof shed (eventually) that is a real bargain. Follow the instructions closely. Try to do it on a day with no wind of you are alone. Gloves help because there are some sharp edges. There's nothing heavy in any part of the shed. Use a cordless drill/screwdriver, even a really cheapo one will be good enough. Have the torque setting (number on the dial) set low, everybody's tool will be different there, so that the screws bite but don't just spin because this will effect the waterproofing later. Magnetise the bit or buy magnetised tips or bit holders. A magnetiser/demagnetiser is a great item to buy and only costs a few pounds. Make sure every screw or bolt that is on the outside has one of the little fiddly washers. When screwing 2 panels together and the instructions aren't particularly clear always make sure the bigger hole is the one the screw goes through first. Get the ground as level as possible so the doors work properly and look neat. They are generous with the screws, nuts/bolts, washers, end caps etc so not like Ikea here. :) The instructions aren't quite as clear as Ikea BUT backtracking after a mistake/misread is not too hard. Every item is marked, some with a sticker and some are stamped. If you have the space then it saves a lot of time sorting the pieces out by item code. The sticker isn't an indication of which way up you use the panel. I made the mistake of thinking if the writing is the right way up then that's the way to install the item. My build is waterproof the doors close perfectly. I had to slightly bend back some of the edge trim that sits just outside the door, I think I caught these with screwheads or something. It looks extremely smart and is a nice wide doorway, the doors slide very smoothly. The holes for your lock are 1cm circles and they are 9cm apart. I haven't sorted out a lock yet. The only tools I used was my cordless drill with the screwdriver bit, 1 screwdriver a 7mm socket (easier than a spanner) 1 small hammer to tap the point protectors that stop you shredding your hands on the exposed screw tips once the build is complete. I wore gloves for some parts but I'm not good with tiny screws, nuts and bolts with gloves on. The nuts are really fiddly. If you put 2 nuts in the socket and gently spin it then the bolt will easily pick up the nut so you can tighten it, you'll see what I mean with a bit of practice. One huge problem was that the top joint on the roof is only protected by a thin roll of tape. There is a trim above BUT it is so high above that you can easily put your hand between. This is not good enough an that's why I knocked a star off. Luckily I ha a tin or roof repair tar for a different job I need to do on my house. I tarred over the tape with a brush and got a strong waterproof seal that will last for years and years. If you buy that same tin then make sure you mix it really well as the lovely smelling resin floats to the top. ALSO wear gloves and clothes you don't mind getting manky because it's a messy job. Give yourself a day to do it, get another person too. I'd have struggled on my own. The roof is near impossible alone AND I had to go off plan there. I couldn't do it in the order they give. My work platform and ladder were good BUT I'd have had to lean over a crazy amount to do it their way. I also bought a bike shed from the same company and they look great together.

Great metal shed for mobility scooter & storage
The 2 men who put the metal shed together for me on a freezing cold windy day both stated it was the smoothest & easiest shed they've put up to date, liked the fact both doors had runner wheels & the instructions where easy to follow too. Looks great with the wood effect very nice my neighbour thought it was a wooden shed at first. Ha ha & my granddaughter has now evicted me & is squatting she has turned it into her own personal playhouse although I have bought it to keep my mobility scooter dry & safe & for other garden items that needed the storage space. The only issue which will need to be sorted asap is the build up of water on inside on the roof lots of condensation inside the shed water & electric scooters don't mix well, have been advised to use cans of expanding foam around the internal edges at the top which also to put insulation on the internal walls not really fire retardant which could potentially be an issue with insurance company if there's a fire. Apart from the condensation. Great looking wood effect metal shed. Definatley good value for money compared to the many other companies price definatley better all in all its good solid long-term storage investment glad I got it my granddaughter really loves it too. Thanks Duramax 10 X 8 Top shed wood effect

Excellent value for money.
Had a good deal on the price. Solid shed. Very good quality for the price. Needs two people to build ideally on some parts. Ensure foundation is done right is key. Perfectly waterproof had many downpours and nothing gets through. Well designed and thought through. Doors slider gets a little stuck, but not an issue.

Easily the best shed we’ve had! Highly recommend
Love this! It’s easily the best shed we’ve had and it’s our first time getting a metal one but honestly so glad we did. The quality seems great and it looks amazing with the wood affect, we’ve received severely compliments already :) It took two people near enough a full day to build this but was worth it. We would recommend screwing it to the floor to avoid any leaks from the rain. Highly recommend this shed.

My old one was damaged and I got this Duramax shed which the package arrived in perfect condition, the build up of the shed was very easy. The instruction manual is in very details which helped me to build up the shed without any problem. This shed looks to be top quality and the number one shed in the market. Tall shed with lots of space inside, doors are opening and closing very smoothly and my garden looks much nicer now with this shed. I will also buy the Duramax Storeaway and a cushion box made by them. This brand is highly recommended! The finish and the quality is the best one in the market for me. Mein altes war beschädigt und ich habe diesen Duramax-Schuppen bekommen, der in einwandfreiem Zustand verpackt ankam, der Aufbau des Schuppens war sehr einfach. Die Bedienungsanleitung ist sehr detailliert und hat mir dabei geholfen, den Schuppen problemlos aufzubauen. Dieser Schuppen scheint von höchster Qualität zu sein und ist der beste Schuppen auf dem Markt. Hoher Schuppen mit viel Platz im Inneren, die Türen lassen sich sehr sanft öffnen und schließen und mein Garten sieht jetzt mit diesem Schuppen viel schöner aus. Ich werde auch den Duramax Storeaway und eine von ihnen hergestellte Kissenbox kaufen. Diese Marke ist sehr zu empfehlen! Das Finish und die Qualität sind für mich die besten auf dem Markt.

This really is a great shed. It is worth the effort to put this together. This is not a complicated build if you are patient and read the instructions which are quite straightforward. The end result is I think you will agree is very good. Gloves are recommended. This is the 10'x8' and you can fit quuite a few 90x40x180 racks in with very little loss of space in the corners of the shed 100% recommended

Utiliser pour ranger du mobilier extérieur durant l'hiver sur ma terrasse il est parfait. Il m'a été livré chez moi en un seul paquet de 80kg en excellent état et dans les délais prévus. Si le prix est un peu plus cher que d'autres ça vaut le coup l'aspect est agréable il est étanche. Prévoyez de le poser sur un endroit bien à niveau pour ne pas avoir de souci avec les portes coulissantes et surtout si vous avez 2 mains gauches mettez des gants (non fournis avec) pour éviter de vous couper mais avec un peu de soin nous avons fait sans et pas eu de coupures. La notice est claire et détaillé en pas à pas. Pour le montage déballez tout classez les éléments selon leur code (le code de certains éléments est un peu difficile a voir quand il est graver un simple feutre noir pour le rendre plus visible sans chercher au montage et le tour est jouer). Je mesure 1.60m pour 55kg et ma compagne est un peu plus grande sans être un super bricoleur elle encore moins nous n'avons eu aucun souci de montage. Ce n'est pas un travail de force mais plutôt de précision et avec un peu de logique te de soin aucun soucis. Etant dans un endroit abrité je ne l'ai pas fixé au sol sur mes dalles de terrasse mais la visserie est prévue et si vous êtes dans un terrain plus sujet aux intempéries diverses un kit de fixation est recommandé dans la notice (à acheter en plus). Un simple tournevis et une clé plate, un escabeau et une petite table de jardin pour assembler quelques pièces ont suffit (oublier les tournevis électrique qui vis trop à fond les vis tournant ensuite dans le vide). Il suffit juste de faire un "puzzle" en regardant les images et en prêtant attention au sens des bords de pièces. N'oubliez pas la petite pièce longue au dessus des portes avec l'étiquette Duramax avant de mettre le toit elle passe un peu inaperçu sur la notice dessin 32. Pour ajuster correctement ne vissez pas a fond les pièces sur les extrémités et vissez en croisé quand tout est en place refaite un tour et serrez toutes les vis quand la base est montée idem pour les côtés. A aucun moment nous n'avons eu a repercer car il y avait assez de jeu pour que les trous prévus soient alignés. Ensuite idem pour le toit, n'oubliez pas la bande goudron avant de fixer le haut et mettez des gants quand vous enlevez les plastiques de protections sur les parties avec aérations se sont les plus coupantes. Enfin nous avons refait un tour de vis pour ajuster le tout comme pour les autres parties du montage. Pour les portes montez tous les éléments dessus, et posez les en dernier en prenant soin de les montez en vous appuyant sur les côtés afin que les bords verticaux s'emboitent au bons endroits sans quoi elle ne se joindront pas correctement sur les côtés. Sans stresser nous avons mis une journée et demi pour un rendu vraiment top maintenant reste à voir dans le temps... mais vu le revêtement ça devrait bien résister. Il me reste à vous souhaitez bon courage en espérant vous avoir aider au mieux.

Stoker une tondeusemais... Si pour le montage pas de problème, les problèmes arrivent quand il pleut, la plate-forme est trop grande pour le chalet, quand il pleut l'eau qui tombe du toit s'infiltre dans le chalet, ou plutôt inonde le bois, les portes bien que fermées l'une contre l'autre laisse passer la pluie, obligation de mettre une corniere comme couvre joint ansi qu'un revêtement autour du chalet pour récolté l'eau, n'est pas constructeur qui veut,. .

Pacco arrivato nei tempi previsti, un solo collo questo evita disguidi o consegne a metà peró è abbastanza pesante, circa 70 chili. Il materiale risulta abbastanza solido, le istruzioni per il montaggio sono chiare ma vanno lette con attenzione e seguite. Tutti i buchi preordinati combaciano nel montaggio e non è complicato montarli. Da solo mi ci sono volute circa sei ore in due è più semplice. Consiglio di scegliere una giornata senza vento per il montaggio, di usare un piano d'appoggio uniforme e livellato, di avere un buon avvitatore elettrico ed usare punte magnetizzate. In generale personalmente valuto un buon rapporto qualità prezzo
