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.

Easy and effective
This was purchased as a trial. Wanted to update tile grout, but be able to remove if it looked pants. Some people don't like the grey (looks unhygienic) but it's on trend and alters the looks of a utility room / kitchen. Personally we think this works well. Its not a substitution to removal and re-grouting at all. It's a quick makeover that can be removed easily in the future if necessary. I would not use this in a bath/shower room as the ink comes away with hard scrubbing but for splash-backs it seems to work fine. I am quite meticulous so I went over the areas three times to make sure lines were straight and all white was covered. The pen is simple to use and cleans off the tiles with a hard wipe. So, quick detail change fine. Complete renovation not good enough. If you are careful, this can look great. If you cannot draw a straight line… I'd not bother.

V33 grout 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.

I must say this product is brilliant, it`s easy to use and tranforms a look of a room giving tired grout a fresh up lift, I ordered the Grey after trying the Dark Grey on my bathroom floor, I have small tiles roughly one and a half inches, so quite a lot of grout, I was going to do the wall tiles in the Dark Grey but it is Dark so thought it would be to much on the walls even though they are large tiles, hence the Grey, I sent for one just to try the colour out and have just come to order a couple more, it is really well priced with free delivery, and the suppliers are very prompt and both my orders were within time stated.... Would recommend.... :)

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.

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
