Review: Excellent - I am 50 and have been training since I was 17. Mainly gym training, but I have done plenty of home training too. I have been big and strong. And I've been lean and fit. I have a fully stocked home gym in my workshop. So I know my training. Now I've passed midlife, here's what I've got to say about the EISENLINK dumbbell (and barbell): The concept is fantastic. Both the dumbbell and the barbell use the same weight plate loading and unloading system. It's quick and easy and I can change the weight within the one minute break period I allocate myself between sets. It's simple and there is no "twist and go" action, the mechanics of which has proven to be a weakness in even expensive equipment that EISENLINK is competing with. This is "spit and sawdust" at its best and it has been designed to outlive YOU. If you are one of of the "scream and drop your weights" types, then NOTHING but pre-set dumbbells or barbells would serve you well enough. Personally, the biggest guys and gals I've met, tend not to scream and drop things. They control their training (they also never use tripod cameras... if you know what I mean). EISENLINK bars are solid and could withstand that kind of treatment to an extent, but with sensible training and respect for these weights, they could be heirlooms for generations to come. Now. I am rarely impressed with modern products, but this equipment is made with good steel and clever manufacturing. The welds are spot on and the interlocking plates are well designed and hardy. When the locking screws are tightened, there is NO movement of plates and NOTHING will slip off and land on your head during an enthusiastic workout. Being a simple mechanical design, there's little to wear and the chance of anything "wearing out" is pretty much non existent. In a nutshell... EISENLINK have managed to get the engineering right and they've allocated an affordable price too. This spits in the face of ANY competition from many angles. I have been able to whittle down all of my space invading dumbbells and have not had to look back with regret. The only thing I've retained is my olympic equipment and my leg press machine, which I use for squats, deadlifts, barbell bench presses and leg presses. Realistically I could even abandon most of those, but being "old school", I have an attachment to my olympic stuff and my leg press. And they too will be heirlooms. EVERYTHING else in my home gym now consists of two EISENLINK dumbbells and an EISENLINK barbell. I have bought extra plates to really get to the heavier side of muscle stimulation, but with excellent form and slow concentric and eccentric training these aren't really necessary to pack on the fibres. That's all you need to be fit and strong (unless you feel that displaying a full rack of 8kg to 50kg dumbbell pairs will impress your mates! I prefer to display my results!)
Review: Excellent build quality – solid metal and built to last - ⭐⭐⭐⭐⭐ Excellent build quality – solid metal and built to last I’m genuinely impressed with the Eisenlink 4–36 kg adjustable dumbbells. The build quality is outstanding — all-metal construction, extremely sturdy, and feels premium from the moment you pick them up. There’s zero rattling or looseness, even at higher weights, which gives a lot of confidence during workouts. This was a replacement for my previous adjustable dumbbells, which were made from cheaper materials and didn’t even last 12 months before failing. On top of that, the customer service from that brand was shocking and completely unhelpful. In comparison, Eisenlink feels like a proper long-term investment rather than a disposable product. Weight changes are smooth, the locking mechanism is solid, and overall it’s clear these are designed for serious use. If you’re tired of flimsy gym equipment and want something durable that will actually stand the test of time, these are absolutely worth it. Highly recommended. 💪

### ⭐⭐⭐⭐⭐ Sturdy and compact
*by A***A on 22 February 2026*

Well done dumbbells, with good weight and compact. It doesn't take too long to change the plates, less than the time between sets, so it's not a great deal. The plates then don't move at all, so I'd rather spend a few extra seconds and make sure they won't fall or move during exercises. Be aware, the plates are NOT compatible with the octagonal version of the same maker
