Review on Durable Stainless Steel Pet Training Collar For Medium To Large Dogs - Darkyazi Pinch Collar In Silver (XL-23.62 In×4.0Mm) by Brion Pine

I have used these collars to train dogs for many years. I decided to purchase this one due to price and the misbelief that they are all pretty much the same. WRONG. I sized the collar to my dog (lab/heeler mix puppy) and went for a short walk. Everything seemed fine. However after about a week of use, and longer walks, my dog began pulling hard because of a neighbor's dog barking at the fence. When I gave a sharp pull, to correct the pulling, she yelped. The rest of the walk was uneventful. I gave her a bath a couple days later and found a large scab on her neck. It was in the shape of a tear drop. I checked the collar and sure enough, the prongs have not been ground smooth, but rather are just cut pieces of wire with sharp edges. Instead of tightening, some grab the skin and in this case tore it. DO NOT BUY THESE! They are cheap, because they are cheaply made.
