I don't own one but I've used one. It's super clunky and has a very "rubbery" feeling, if that makes sense. When I work out I like hearing metal screatching, it sets the proper beat to the workout routine. That thing is very monotonous and doesn't give you an even feedback. In general, it's a POS.
If you decide to go to a gym, stay the fuck away from large gyms like Bally's. For more info look here:
