I've bought one today. I'm struggling maintaining. I'm doing it by watching what I eat (or so I thought), gain a few lbs, then have a few CD shakes to shift the weight. I am managing to maintain, but I know exercise is the answer. I've already got the lateral thigh trainer, so now with the mini trampoline I'm sorted. Tonight me and my 10 year old are having an exercise session (LOL...she's a stick insect, but loves going on them). We are going to get some music on, plenty of water and we are going to have fun. I had one about 10 years ago (I've no idea where it got to!!) and after I had my daughter I shifted the weight in about 2 months. I don't know why its taken me til now to remember this, but better late then never. I'm looking forward to it.
