Worked great to make my front entry tiles looks brand new. Only issue I had was that the end of the marker got really soft really fast. Because grout is pretty rough the end of the marker got soft and flimsy pretty quickly making it hard to make straight lines and hard to get the grout to coat well. Otherwise was a great product overall.

If you want to touch up a few tiles this is fine. Anything bigger and you will probably not be happy with this .

I wish the tip was longer so I didnt have to be pulling everytime. Other than that, it did what it was supposed to. Would buy again.

You have to shake this very well and for a few minutes to get the paint to wet the tip. Very smooth. I wish the tip was thinner yet it worked very well. Dries quick. Excess cleans easily. I highly recommend this product.

I like this product it works really well on the grout; however, it’s a little pricey for how much area it does

I like this and the fine one works better for me. I just think that buying the fine one you shouldnt get less product. With the thicker ones you get a lot more. Also, I dont care for the replaceable tip. Found the other one easier to use.

Initially I had trouble getting the pen to work. After a bit, I was able to get it going. Hopefully now that I have used one and know what to do to get it started the next one will work even better

I used this for my bathroom floor. The floor looks great and new. Very easy to use.

Does exactly what its advertised to do but make sure you actually have WHITE grout before using it, otherwise your results will be freakishly bright. Wish they made these in other colors, like pale grey and beige...

I rent and can not get my nasty grout replaced. This worked nicely, although I needed 3 for my small shower. After a few months it’s looking grungy again. It’s good as a temporary fix but it’s not going to solve any problems long term.
