Review on 📸 Harwerrel Tripod Mini Ball Head: 360 Degree Metal Ballhead Mount for Camera, DSLR, Cell Phone, Monopod, Gopro & More by Dana Jackson

The black plastic tension knob is held on the screw with only glue and the end of the screw is rounded. My cocking knob broke the bolt and because the end was round it just kept turning and I couldn't loosen the scope. Luckily I wasn't out hunting at the time, and now I'm replacing that junk. I've tried gluing the bolt to the grip, but if you push the bolt all the way into the grip, a normal person will decide the bolt is too short to work. Terrible design!
