What are your fitness gadget or accessory fails?

Oh wow, I had a Body Blade. That was a big bomb, though I was able to resell it.

Ah, I've wasted money on soooo many gadgets...and I'm sure I'm not done, lol. Most recently: I bought a Fitcuff to use with a Leslie video, and then after not using it, I donated it to the thrift store. Then something convinced me that I NEEDED it again, so I rebought it. Ask me how many times I've used it in the months I've had it. (spoiler alert: the answer is ZERO!)
