I grew up with a trampoline but haven't been on one for many years. In my sixties I want to get and stay fit after shattering my knee a few years ago. I have thoroughly enjoyed the Bellicon which I have waited for years to buy. Wish I had purchased it years ago. I use it to break the monotony of sitting at my desk for hours, doing quick 5 to 10 minute jumping breaks to increase my energy. I also use it when I watch TV at night. I have had no negative repercussions from using it regularly even with a history of osteoporosis and previously broken bones. Overall, I have more energy, sleep better at night and know that the work it does to drain my lymph system is a good way to combat cancer that is rampant in my family.
I purchased the 49" Bellicon as I am fairly tall and wanted the largest space to be able to do the largest variety of exercises possible. Although the rebounder looks like a small trampoline it has a sturdier bounce that makes it better for various reasons. I am 5'7", 130 so I have the "strong" bungees. Mine has the folding legs which are very sturdy and make storing it away easy when needed. For the most part it stays open because I enjoy jumping daily.
I highly recommend Bellicon and believe no other brand is equal. Their customer service is exceptional. I received my well-packed Bellicon in about 4 days. I could not be happier to have made this purchase.
