I bought this for our 4 people band thinking of those occasions when the power and/or mixer is a bit far from the scene.
Before buying this I had read comments about it having a heavy smell but otherwise being a good product.
It is true that the mat smells heavily, so for the first time we used it (indoors in a small venue), I left the mat outside in the garden for a couple of days, and that helped a lot.
We have now used it indoors and outdoors and it works quite well. It is heavy enough, so it doesn't get blown by the wind, and sturdy to resist people walking on it.
Totally recommend it.
