Review on 🐶 Highly Efficient PATPET Dog Shock Collar for Large Dog - Rechargeable, IPX7 Waterproof with Remote Control, 3 Modes (Beep, Vibration, 16 Static Levels) for Training 2 Dogs by Carolyn Lawson

I just received these collars so this is a VERY preliminary review. So far I'm happy with them. They appear to be a quality product and appear to be durable. The waterproof charging port cover feels solid and looks like it could be removed and replaced over time. It's a bit bulky for a small dog, but most of them are. They connect to the channel automatically, unlike some other brands, which is a definite plus. They're quick to respond to a button press without turning on the screen, another plus (and the feature is absent from some other brands that require you to wake up the screen before a command can be issued). Volume is good. The vibration is adequate, although not as strong as some others I've used in the past. I like that there are only 16 of them.The level of shock stimulation. Models that have up to 99 are ridiculous in my opinion and I'm very suspicious of them. Based on testing on myself, I wouldn't go above 5 for my medium sized dogs. I found it quite awkward on that level and remember the idea here is not to hurt your dog but to get his attention so he knows he's doing something you don't want him to do. in that there is no ring to attach a tag or leash to these receiver collars. During the absence of COVID, all of my dogs at dog parks wear training collars. Just in case they're out of earshot and I need to call them. The lack of this feature makes it impossible for me to do this. I'm deducting a star for that, I'll update later.
