The fitting of the Regupol interlocking tiles is perfect - the best I've seen - which is the most important part of interlocking tiles. Time will tell if shrinkage occurs. Premium quality though - deserving to be offered through Rogue. As a general rule with tiles it is best to install them cool - rather than warm - so that gaps don't emerge if they are installed warm and then forced to shrink if the room cools. The jet black tiles (no colored flecks) that I bought have a very slight curl to one side but can be flipped over - both side appear the same. Be careful to set the interlocking matching correctly, and with the (very slight) curl side down, before cutting spaces for posts. That (very slight) curl is far from significant enough to discourage anyone from buying them. They are about 1/32" less than 3/8", so they won't be perfectly even with 10mm tiles. Packaging from the manufacturer - not Rogue - is minimal; single wall cardboard (one side of one of the boxes split open in my shipment, but no damage occurred to the product). The off-gassing is perceptible but not overpowering and disipitates in a few days. To install tiles I press the interlocking tabs in one at a time at an angle and then flatten rather than pounding down with a hammer. (Press to one side then press down.) From experience it is both a luxury and advisable to set the area that you think you'll need and add a row of squares around it. Yes, this will increase your costs, but having that buffer around your workout area makes movement around the space freer. (Everyone needs a buffer.) (Very good Rogue customer service as usual resolving a minor issue importing into Canada.)

Fantastic rubber flooring. Lays flat. No smell. Laid it down by hand and used a rubber mallet to lay the seams flat. Pro tip‐ use a jig saw to cut the pieces near the walls. It's much faster than a utility knife. This flooring is worth the price.

Very easy to put together, recommend a rubber mallet to quicken things up a bit. Kids already walked on them with their daily shoes to leave footprints and was rather easy to clean up. Not sure if it was my batch of tiles but the "Firestorm Red" is a tad more on the orange side of the color scale than what the picture shows.

I wish there were thicker variants of the tiles that are interlocking. Regardless, this was sufficient for my needs and I really like them. No rubbery smell as other people have mentioned. Great purchase

I replaced my horse stall mats with these. They feel better under the feet, look nicer and don't smell nearly as much. The air finally feels clean again. The only downside is that fitting the interlocking mechanisms was annoying, but the portability is worth it if you see yourself moving the gym later.

Bought these after a failed attempt at using horse stall mats as gym flooring. No matter what I did, I could not get rid of the intoxicating rubber smell of the horse stall mats. These tiles are very nice and definitely worth paying a little bit more for. They fit together seamlessly, and you can’t tell that they are separate pieces. If you need flooring for a smaller space, I would recommend these over the hassle of getting a large roll and having to cut it yourself. The best part is there is no rubber smell!
