To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is one of those thing it’s best to save (lots of) money and stick with the basic ones. The springs in this thing is clicking and smacking away through the movements and makes for a not smooth roll. The grips are meh at best. I wish I still had my old school simple one that I had for 20 years that I payed less than $10 for. The things that make this different than the simple design are the things that take away from the workout for me. More money for less of a workout.
After using it a while I could hear the hardware on the inside start making clicking noises then just failed completely. The wheel can roll out away from you but you can't roll it back in towards you. Definitely not worth the money, I'd go with something similar in design but without the guts on the inside, keep it simple.
