the only thing I'll say is watch out for the cheapies, it seems the way they save money on production is that instead of using cinch straps or ratchet straps they usually provide ropes for attaching them to the tree. The cheap ones I've got have a really small nylon rope to tie them to the tree, I just don't trust them for an entire season I'd prefer the nylon straps if it was up to me. Worth a little extra money
