We had them. I threw them all out and would not get them again. The sticky things are basically clear stickers that you apply to the underside of the tiles. They hold reasonably well and do not stick to the floors. You can buy extras in case you need to replace some of the tiles.

I did not like them because the tiny gaps between tiles were big enough for dust, dirt and sand to filter though. My floor under where the tiles were is scratched up--I do have kids and they definitely tracked in sand despite my efforts to prevent that. Also, they are not very cleanable. Ours were mostly and oatmeal color and they showed grime and dirt quite easily and I could not get them to come really clean, not even when I took them outside and scrubbed them with dish soap and a scrub brush and then tried folex.

I've been satisfied. The tape dots hold the tiles in place securely even after pulling one up to wash it in the sink (dogs). I've been able to clean them much better than spot cleaning a rug. I haven't had the experience with dirt seeping between the squares. For my purposes Id make the same purchase again.

Thanks for the input. Maybe I'll try a small area rug in the bedroom to see how it does before committing to a big area rug in the family room.

I once knew a "green" interior designer and she use them and loved them. But I cannot say how the clients felt. They were in our office and I didn't notice a big dirt problem, but that was not a high traffic area and she used the bright colors. Sounds like they would not be good for a heavy use application. I have oatmeal colored Berber wall to wall, and it is a huge pain to clean, that is for sure. Flor makes different levels of squares, some are designed for high traffic.

I've had them in kids' bedrooms without any problem. I've had them in high traffic entries, and there they didn't work as well. The tiles kept separating from each other. In a high traffic area, I'd order extra "stickers" and use twice as many as you're supposed to.

Not great for high traffic. They are cool, though.

We have them in our workout room and they work great! I wasn't sure if they would stay in place during a floor workout, but they do. And we vacuum them regularly with no problems.
