Are they any good? Thinking about a cheap mat primarily to go under the wall I have in the garden, which now has a roof about 5' off the ground. I'm not a serious boulderer ( Sally in the Woods is my closest bouldering, so I'm not likely to use it under serious rocky landings.
I'm also pretty old school, in that in my formative years at Pex Hill Quarry, a car amtt or a beer twoel was the height of sophistication!
Thanks,
Steve
