The unit is well built and sturdy and will not tip over. Shipping took a little longer than expected but it is worth the wait. This review is 4 days after assembly. I can only stay inverted for 10 to 15 seconds at this point and I can do exercises that I thought were not possible for my size. Customer service stayed in touch via emails so communications was not a problem. This review is 4 days after assembly, I will add more as I have more time with unit.
