Do some more research please. Cheap rebounders from Walmart or anywhere else are NOT the same thing. Those are called "mini trampolines" because that's what they are. They are toys even if you got it out of the "Excercise" dept.
If you want to "Cleanse" You need a high quality rebounder like Needak. Even if you don't go with Needak, at least go to the Needak website and read and understand the differences between a GOOD rebounder and a cheap Walmart one. Needak cost $200, Walmart's cost under $50. You get what you pay for.
