Great cheap option
After literal months of scrubbing and googling ways to refresh grout, I finally took the chance of trying these pens out. I thought it was going to look like cheap paint but it soaked into the grout great and totally gave the kitchen a new look. I did go over everything I did with the slightest bit of a damp rug to make it blend better. Would definitely recommend for a cheap quick fix. I used the light gray option

So I ended up using 2 grout pens. This large light gray one and the small beige one. After my first cleaning of tile/grout and use of this pen I felt like the gray was too bright and it had a slight bluish hue. The last pic was the dirty tile I started with. The first pic is how it looked after I cleaned it and then used the light gray pen. The second and third pics are how it looked after I went back over the grout with the small beige pen. The two-toned contrast I ended up with is better than I could have imagined. I am very happy with the end result. My only complaint would be that the felt tips on these come out kind of easy. So you have to keep putting it back in. Other than that, i found them easy to use, long lasting, and well worth the affordable price.

(I'm amending my original 1-star review.) One of the pictures shows the intersection between grubby grout and the painted grout. The 2nd picture shows more of the painted grout. In natural light, the tile and the grout are nearly identical in color and depth. The grout paint is the Light Gray. The tile is a light blue color with variations that are sort of like very thin clouds drifting across the tile. If I could buy a jug of the Light Gray grout paint to use with a small brush, I'd do it in a heartbeat. The color looks great with the tile and I suspect that touch-ups would be a breeze. Alas, that is not to be.
This would be great if you need to touch up unsanded grout between smooth tiles. My floor grout is very rough and the floor tile has a slight pebbly surface to keep it from being slippery. The combination of those rough surfaces basically shredded the felt tip, which is like a marker tip. It also made it challenging to wipe off the excess with a damp cloth. The excess was more and more problematic as the felt tip became fuzzier and less accurate.
I decided to start in the laundry room, where mistakes would be seen by just by me . I sampled it on a few lines and let it dry overnight. Then ran my floor scrubber machine with an ammonia-based cleaner. I was happy (and surprised) that the paint held up just fine. (I've since learned that ph neutral cleaner would/will be much better for grout!)
But when I went to do the entire laundry room, I quickly realized that the tip was getting fuzzy, which meant that paint was dragging onto the adjacent tile. It also took considerable pressure to get the paint to flow, despite shaking it frequently. Because the tile is rough, wiping off the excess with a damp cloth was a real pita. (I'd already checked and the replacement tips for the wide markers are not in stock, though the company said they expect them to be in within a few weeks.)
Reaching the company just to find out if they *make* the replacement tips was a big nuisance. Their contact info is not on the product page. Contacting them through my Amazon account required several steps and then waiting for them to reply to my email.
Overall, I would've loved the product if it came in a bottle and could be applied with a brush. There are other products that use that technique, and I found one from This Old Grout where they will match the original grout color. (I ordered a small bottle to make sure it's going to work. It requires more prep work than the marker, but I expect it to be a lot easier to apply and get good coverage.)
As I started to say, though, for small areas where the marker tip will survive, this product would be fine. Too bad I'm going to have to prep and cover it with the final grout colorant!

I like these pens. They are very easy to use and quickly restore dirty/stained grout back to uniform color. No mess and no fuss. However, this came out more "light blueish" on our bathroom grout which was not what I was expecting at all. See the photo which clearly shows the grout color does not match the cap color.
Update: EXCELLENT customer service contacted me and made this right.
