The quality is great. Looks and feels much better than the normal horse stall mats.

I originally purchased these tiles to use as flooring in my Rogue deadlift platform. Honestly, I didn't love them for that purpose. The tiles aren't all uniform in size and it resulted in big gaps between tiles that the barbell would then roll into. This would make the bar sit uneven on the ground a lot of times. It was annoying. I replaced the tiles with double 3/4 inch gym mats and have been much happier with that setup. That said, these tiles are still awesome and very handy. I use them all the time to perform rack pulls and deficit deadlifts. I also use them with the Rogue adjustable box squat box. I keep the box set at it's lowest height and add these tiles on top of the box to raise/lower the height for box squatting. Anytime I need to raise the height of something a few inches, I add these tiles. They are lightweight but very dense and strong. They are definitely worth having for their versatility in many applications.

These are very heavy duty and work great. I purchased the crumb finish and have been very happy with all 12 for my hone gym

I wanted to use stall mats and double them up to make them as thick as these tiles. But running the numbers, these only came out to be a few dollars more than double stall mats. So I went with these since they're easier to handle and they didn't smell.

I purchased a few extra tiles in addition to my deadlift platform. These are perfect for many uses in my gym.

Bought a few months ago. Sturdy enough for me to go deadlift on. Extremely glad I bought these.

I bought these to replace stall mats--the better noise reduction overall and does not require a bottom layer of wood.

I ordered a couple of these to provide more protection for my floors. My setup is inside my home and I wanted a little more reassurance that dropping weights would not damage the concrete under my gym floor mats. They are thick, study and don't slip on my rubber floor mats. I ordered the crumb finish and am happy with them.
