just got one a couple weeks ago. It it about as safe as u can get. u have a safetey strap around the tree as you are climing and once u get all set up then u take the safety strap off and there is no way u could possibly fall out. I havn't actually sat in it for a long period of time yet but as long as u have 2 tree pegs in the tree u could stand on u should have no problem sitting in it all day. I would have to say so far i love it. I'll wait till the season opens before i give it too much credit
