Bests & Worsts Reviews from Amazon

This is one of those products that has a lot of upsides but several downsides. To preface, I have a roughly 20-square-foot white tile floor in my apartment bathroom. When I moved in, the grout was very discolored and made the tile look dirty. I was extremely skeptical about this product, but it was a reasonably priced solution and a top seller on Amazon, so I gave it a shot. I followed the very simple directions on the pen (clean floors, remove cap, shake pen, use), and was initially amazed by the results. My nearly gray tile grout was being transformed back to white. Although, after I got through about 6 square-feet of tile, the pen tip started to fall apart. Was it still usable? Yes. Did it hinder the quality of the paint job? Also yes. Additionally, the paint ran out much quicker than expected. I was able to get a single coat on the entire tile floor, but the 60 meters of coverage they claim is a little far fetched. Nonetheless, my tile floors look good. A couple tips (no pun intended): get two pens because the coverage is less than advertised, apply 2 coats, REALLY clean the floors before you start (I didn’t deep clean nearly enough and the grime made the paint job much harder), consider another solution unless you have white tile as well (I feel as if this pen would not be great if you needed to be precise), and don’t push as hard on the tip to increase the pen’s longevity. Hope this helps! Still a good product, just a couple things to keep in mind before you buy.
