I am very happy with my "Power Tower," which, by the way, lists for $1,000 on the Weider site! Design and manufacturing is good with a nice coating on all metal parts to protect against corrosion. No parts or hardware were missing from the package. The tower uses lock bolt connections which are strong and have back-up plates at stress points to prevent separation. Welds are not perfect, but they will not break and it is not an airplane! The structure is heavy enough so that the tower will not move around in use even by 200 lb. plus people. Instructions were good and assembly by anyone who can use a box wrench and screwdriver is a no brainer. It helps to have a buddy to hold heavy parts while you are bolting them together. It took me about 2 hours, but I am very slow and deliberate to avoid mistakes. Overall quality, fit and finish were much better than I expected for this price. A real bargain! Of course, you will have to make a commitment to regular use in order to get the benefit!
