The Stamina 36 Inch Folding Trampoline has been great. I like using it with virtual running videos on youtube or watching regular TV.  If I only have a few minutes I can still get my heart rate up. My only complaint is set up.  I had to have my neighbor do it and then I worried about the clips being correctly in place, what would happen if they weren't, etc.  I've been using it for about 6 weeks and all is fine.
