I ordered these mats because I just wanted to protect the soil and at low cost in the newly refurbished gym. Requirement: protection as a base and Kettler multi gym and protection when moved by heavy weights. Both meet these mats without hesitation. For laying: the mats easily assemble like a puzzle and use the end pieces according to the edges. In my case, the room size was not quite fitting, therefore, had to be reduced accordingly, a page on the wall. This has been no problem with a normal pair of scissors!
The delivery was made incidentally well packed in cardboard boxes and foil (sealed) within 3 business days.
Very good P / L ratio, decent quality. Strong buy recommendation.
