Very disappointed! I absolutely loved this board and the CD that came with it, but I wish I had read all the reviews before purchasing to see how many complaints there are about them cracking. I would go home every day and do at least 2 work outs, and I could really feel improvement, especially in my core.
I only weigh 160 lbs, well under the proclaimed 400 lbs. It is past the return period, so I am out the purchase price. I have not been able to find a contact for the Simply Fit customer service other than to order another one, which I will not do.
Unless you can afford to throw away $40 every few months, do not buy this! It seems that all the complaints are pretty much the same, time period after return time is past and well under the 400 lbs.
Bottom Line: No, I would not recommend this to a friend
