I have the Tech Tubes. However, after over a year the drivers side bracket let go on me with all my weight on it. I crashed my right knee into the door sill and drove the knee cap up. I just came from the orthopeadic surgeon and I have a torn cartilage, possible partial tear in the patella tendon and damage to the back of the knee cap. I contacted Tech Tubes and I also found that the one bracket was faulty, in the metal... something that Tech Tubes would not have caught... They are sending me new brackets. This is not to bash them but a heads up to keep an eye on the brackets as I probably would have caught this if I was checking. Now I am booked for a knee scope... right in the middle of my plans for competing in strongman this year. Perhaps this mishap will help others to avoid this kind of trauma.
