Wife bought the rock stepper and it broke twice!
Wife bought the rock stepper and the welds broke on the part of the rocker that supports you foot. It broke within the first couple of weeks. Good thing it was under warranty and on the plus side they sent out a brand new one right away which is why they get 2 stars and not zero. The second one lasted about 3 months and the welds broke again. This device is not constructed very well and I would advise anyone to not buy this until they sort out their quality control. For context my wife only weighs about 140lbs and she only used it for about an hour a day at a casual pace. I can only imagine how fast it would break for anyone heavier and trying to get a serious workout.
