Works fine, that's what matters

Result first: If the part is, it does its job very well. For us it comes to protecting a sensitive cork from damage by the rollers of an office chair. I ordered the transparent version, in which you can still see the ground below.
Some Bonus information:
- The protection mat has not smelled or stunk
- You get the floor mat a an elongated package in which it is rolled. When "Open" the role some caution is called for, because it spreads out jerkily.
- The floor mat is quite a bit bulky. It's good when you can unpack in one place, is on the court. This is even more than the floor mat is full surface protected by a bluish plastic sheet that you have to deduct only.
