I finally bought my mini-tramp, and I love it! I have it in front of the TV, so I just jump on it while commercials are on. It's neat, because it's hard to walk by it and not want to jump on it <img src="i/expressions/face-icon-small-smile.gif" border="0">
It's been great for my knees, and when I'm done, I feel great!
I got mine at Walmart for $23, but it was hard to put together. I couldn't snap it myself, needed someone stronger.
