Bests & Worsts Reviews from Amazon

They change the puzzle interlocking pattern every time I try to order more of these... If you get all you need the first time, they're great, but if you ever intend to buy more, beware, they'll probably ship you a model that doesn't fit with whatever you bought before. I first bought some puzzle mats back in 2012 (essentially the same thing, just different seller, brand and mat thickness), I loved them, wanted to expand the area I was using them for and spent several weeks buying/returning orders because they were different than those I had originally purchased. The same is true when I bought about 8 sets back in Oct 2018 and 4 more sets in Mar 2019 - I used the "buy it again" option in Amazon but the model sent in March was a lighter color and different puzzle pattern than what I purchased in Oct. That issue aside - the mats are great. They look good, durable, easy to install and protect the floor in my home gym. If it weren't for the annoying issue about ordering more, I'd give them 5 stars.
