Review on Trimax TRZ8AL Aluminum Adjustable Receiver by Martin Masaniai

Design requires you twist two balls together and then insert a small screw to secure. After leaving my system plugged in all winter, a small screw got stuck and came loose when I went to clean it. (A 2" diameter sphere contains this screw which then absorbs rain/snow over time). I was thrilled when I saw that I could purchase a set of spare balls. The replacement kit was not properly tested because the grub screw was not centered! After the balls were tightened, the set screw could not be installed. So I bought their only 2 inch ball. The shank is not long enough to hook more than 1.5-2 threads when you could actually hook the nut. Very dissatisfied.
