Impressive!
I was really impressed with this grout pen. I used it on floor tiles in my ensuite bathroom. It went on lighter than my original darker grout but looked great once finished and completely refreshed my whole bathroom floor. The nib was a bit worn out at the end but managed a decent sized area with no problem. I intend to buy the white pen to go over my shower area.

Worked great. Very easy to use, dried quickly with the perfect finish.

Great product if used correctly.
So there's a nack to this ! Shake it loads, If you use a piece of card (I used the back of the packet) and press it down for 10 seconds then draw a line on thr grout and repeat, the paint will come out consistently and you can have a longer lasting nib as you're not dragging the nib on the grouting as hard. At the beginning I was like yes this is amazing, im gliding through this, isn't life great. Then after an hour and a half my back was hurting, I was having an existential crisis, I just wanted it done, and basically ended up getting aggressive and doing it as quickly as possible. Took 2.5 hours in total. I'm not ashamed to say the first part is considerably neater than the second. I am 5ft2 had to do some climbing to get the tops and leaning over vicariously. Overall I'm pleased with the final result. Kicking myself for rushing the end. Used 2 pens as when the nib started to go it looked sloppy. I'm now drinking a glass of wine as I deserve it and it's not even 12 o'clock. This was written by a 28 year old woman on her annual leave. Be warned! It's like adult colouring in with more serious consequences if you go out the lines.

V33 grouf pen every time.
Ok for small jobs. Had to purchase 3 pens even though 1 should have been enough. Everytime you wipe away excess you have to touch up grout line again. Besides that the nib is poorly designed and spurs out making it hard to do a precise line.

Easy to use, good coverage
We bought this grey grout pen to help some white grouting look less obvious in some old drill holes in grey tiles in our bathroom. You can obviously still see the drill holes, they are never going to completely blend in, but the grey grout pen helped the holes look a whole lot less obvious than the white grout filler. Very easy to use and good coverage!

Game changer!
I bought this because my bathroom was looking dull those once white grout lines were now discoloured and it looked awful, I bought both the grey and the white the grey I’ve used against white tiles and it’s literally transformed my bathroom, it looks so modern and beautiful. The white has refreshed my kitchen. Soo easy to use, I did the whole of my bathroom within about an hour. It was actually quite therapeutic and not at all stressful I wish I had done it sooner if I knew how easy it would’ve been. I’ve had it on a few months now, some areas have needed a little touch up but nothing major. So very impressed

Disappointing (previously a very good product)
Unfortunately, I have given one star in all areas. I have used this product before I. My bathroom and it has been excellent. I started to do my kitchen with the old pen I had left over, no problem with it at all and perfect finish again. The pen ran out so I bought some new ones and unfortunately they wash out of the grout quite easily when wiped after application. I queried this batch of pens with the company and was told they need 24hrs to dry at a temperature of 21degrees. I had left the pen to dry for 6hrs as per the instructions on the packet. There is no mention of 24hrs and 21degrees so I therefore didn’t follow it. I again responded with a photo of the packet to the company and am yet to receive a reply. In the meantime, I have reapplied and left it to dry for four days as I’ve been away - gone to clear up where it got on the actual tile a little bit with a damp cloth and again it removes it from the grout. Disappointing product (shame as about 6 months ago this was fab when I purchase it before) and disappointing response from the company.

Begeistert
Super Stift, es kommt genügend Farbe raus und die Mine haltet gut. Davor die Marke „Sanjie“ kauft… katastrophe …. Lieber ein teurer Stift als ne ganze Packung billige 👌🏻 Sieht viel schöner aus. Es ist ein Blau/Grau.

Funciona perfectamente, tono azulon
Fácil de aplicar en la cocina, aunque el color tiene un tono gris azulón. No era exactamente el color que esperaba pero no queda mal.

Easy way to make it look great again
Easy to use, did entire bathroom floor with one pen and the same tip, and there's still more fluid left in the pen, so I can use it for further touch ups
