Bests & Worsts Reviews from Amazon

I like the design of this product, unfortunately for many users the spring which assists users in returning to original position breaks. The internal spring breaks easily with application of minor pressure. The reason for frequent spring breakage is inferior spring material and plastic spring stops used to hold the spring inside the carver. I used the carver on carpeted workout area which increased the return resistance and the spring broke within a couple of days. A carver with broken spring can be opened by carefully removing the circular information tape on the edges of the carver on both sides. And unscrewing approx 6 Phillips head screws set into the carver's plastic body. You will notice the spring inside is held by plastic stop shown broken in the picture below. The broken end of the spring is also shown below. The other part of the spring inside the carver is also shown below. The manufacturer needs to reinforce the spring stops with metal stops which are more durable and should use more flexible and less rigid type of spring which does not break easily and should be able to withstand pressures up to 300 lbs as advertised not 200 lbs when it broken. For now I am using the carver without the spring assist, may be I should have gotten the ab wheel which is sold at a cheaper price if I had known the assist spring was so weak.
