I was a bit worried on getting this not knowing if it would actually work, our bathroom is very old and no matter how much it gets cleaned it always looked dirty. I decided to give this a try and I gotta tell you, I’m impressed! You can def tell the difference, & how much brighter the tiles look. I would get this again! I gave 4 stars because I do wish it was a bit more pigmented, I had to go over the lines about 2-3 times. Overall it’s a great product!

Works but not much in the pen. Would need many to cover a large area.

Its easy to use, except it was hard to get in the thinner grout lines, mostly wasted product on the tile going back and forth to get it down in the grout line. Using a damp cloth, it wipes right off the tile. I dont recommend for price and time, especially if you have small tiles! Im not sure how much I was expecting to get out of 1 pen, but I only got 6 sqft. (Thats 6, 12in by 12in square) I waited a few months to buy this product and now I wish I didnt bother. Debating if Im going to buy 4-5 more to wish my bathroom. Ugh

The marker tip did not last more than 1/3 capacity of marker. I have to cut open the marker top and use a point paint bush to use up the paint left inside the marker. For an average shower tile wall, you need at least 2-3 markers.

Cant tell you if the paint is special compared to a generic paint pen (because thats essentially what you get), but it works!

this transformed our grimey kitchen backsplash grout amazingly. takes time for the paint to come out but it works well, dries out quick tho

I wouldn’t buy it

This little pen is great! I have an old tub and I rent so Im not able to redo the tub and tile. This pen renewed the old stained, mildew colored grossness that was my tub. Its not perfect, but now I can step into my shower without feeling like something is going to come alive and eat me( seriously, my tub was stained black from bad caulk and mildew. One downside of the pen, you do have to press the tip down to get the paint flowing every so often, especially when doing tile above your head. Definitely listen to the instructions and make sure the area is clean and dry or it wont stick to the grout as well. It is really easy to get off of tile if youre messy like me and cant stay in an straight line if your life depended on it. Im getting another one to do the kitchen grout too because some genius put white ceramic tiles in the main entrance to the house.

I followed the directions and the tip wore out before i could finish my project, rendering the pen and remaining paint useless.

In all seriousness, some reviews scared me because they acted like they used this pen on one strip of grout & it ran out. That is NOT true at all!!!! I am using these on my whole kitchen floor & they work so well and do not run out quickly. I think people pushed too hard at first and/or they didn’t try that hard to use it correctly, lol. They’re awesome & totally worth it!
