Review on 🐶 iSPECLE Dog Training Collar: Rechargeable 2600ft Remote Waterproof Shock Collar for Medium to Large Breeds with 4 Training Modes by Chinelo Aranjo

I bought this set of collars after buying an identical set but I don't know where I got them from. I LOVE the original set. The battery lasts a reasonable amount of time, the audio and vibration levels are good (those are the only features we use), and the signal strength covers the entire range we need it for. Well, although this set is identical. Security and functionality is BAD! The battery performance is terrible. You have to charge every day. The lights on the collars are blinking for unknown reasons. no rhyme, no reason. But in the end one of the collars overheated. my poor boy His neck was burned. (Remember, we NEVER use the shock function.) When I took the collar off as he was visibly upset (and hadn't pressed a single button on his collar all day), the device was VERY warm, almost hot! I was supposed to take a picture but to be honest I didn't even think of it. I was more concerned about the treatment of his poor neck. We've had another set for a few years and it still works great. We discontinued all 4 of these collars to avoid this situation.
