Excellent Product!!
Super easy to use! It completely changed my kitchen! You don't need to be extremely careful when applying it, it cleans really easily form the tiles, just wait until its dry and use a dump cloth or sponge to clean it(try not to be too messy either..). If you need to cover some gaps is better to wait until its complete dry before going with the second layer. No need to apply to much pressure, just shake it and press the tip a little bit against a flat surface until the ink starts coming out. One pen was enough for all mi kitchen (it's a small one but still..) and it still has paint inside. This pictures where taken 5 months after I painted it and it still looks like the first day! Amazing durability! No need to keep thinking about it! This product is great!

Really good
Really easy to use and works perfectly. The tile grout I was treating is black and it now looks brand new after being damaged by a bleach cleaner and losing its colour.

Good enough.
It is great, easy to use, neat and covers a great deal. One pen was enough for my kitchen and half of my bathroom. The only thing that's missing for it to be really excellent is an extra tip provided. I found the tip wears quite quickly, so regardless the pen not being empty, you have to either throw it away and buy more, and buy extra tips. But apart from that, it's pretty awesome. BEWARE: I have purchased the double pack after finished this pen (same brand, but not dispatched by Amazon but a different seller) and they are utter rubbish! Let alone I needed both pens to cover half of my bathroom only, they leaked, didn't cover the grout but the surroundings - the ysmudge and stain the tiles, which you can not remove.

Black is risky
I had used a WHITE grout pen on white tiles/white grout and got super confident that black would be a doddle too. Is was not, from a distance it looks ok...but up-close, awful, now I don’t blame the pen, as the grout is very very old and so very wonky,. But,,,sigh...wish I hadn’t bothered ...sorry - caveat to this, if you’re going over more modern grouting with defined straight lines it may indeed work fabulously...just not manky old yucky ancient stuff ...

Fantastic.
This genius bit of kit has totally transformed our kitchen. So easy to use any mistakes just wipe away with ease . I'm so impressed with this grout pen I've ordered more pens to transform our bathroom . The only thing it doesn't cover is silicone or plastic sealant . But as I've used a black grout pen I'm going to use a black permanent marker for the sealant . I highly recommend this magic in a pen . Warning please don't press on hard as this will ruin the nib also if the pen looks as if it's waring out just press it down gently onto some scrap paper or card to get it working again . Leave till it's fully dry before cleaning the tiles .
