Review on OneTwoFit Power Tower Set - Multifunctional Wall-Mounted Pull-Up Bar, Chin-Up Bar, Dip Station - Ideal Indoor Home Gym Workout Equipment, Supports Up To 440 Lbs - OT126 Fitness Dip Stand by Mason Gordon

I agree with many of the other comments here that the overall construction is excellent, but the wall mounts are worthless. Sturdy and solid metal platform once assembled, but the mounts for a concrete wall are absolutely a waste. After drilling holes and installing the mounts into a solid concrete wall by following the directions, both sides pulled away from the wall immediately. No hold whatsoever, so I threw them out and used some concrete screws that I had in my garage from a different project. Happy with the overall pull-up/dip station so I gave 3 stars. Would rate the mounting screws a 0 (or less).
