I really like that they come with all three discs in different lengths. I noticed that the screw holding the swivel head on the one I was using was a little loose. Knowing that if it worked loose while working outdoors, the small spring and index pin holding it in place could easily be lost, I removed the screw while I held the rest of the mechanism in place and stopped, tightened the threads and reinstalled . Once it's cured it won't come out accidentally giving me peace of mind that I won't lose any detail. I went ahead and repeated the process for the other two remaining breakers. I would recommend this to anyone buying these.
