Review on Vsezund Dog Training Collar - Rechargeable Shock & Vibration Collar for Dogs with Electric Stimulation, Beep, Security Lock, Remote Control, and Waterproof Design - Suitable for Small, Medium, Large Breeds by Jessica Lange

I've used many other dog collars from Dogtra to foreign brands and I couldn't find one that worked properly or had good battery life or was even fully waterproof, not just these collars waterproof , but I've got over two weeks of battery life on a single charge and I've yet to charge it since I ordered it. I took two extra collars because I have three dogs, I would definitely recommend them to someone, they are good. Refresh, they lasted about a month with collars without a single charge. I only had to charge them the first time. One thing I would recommend: higher shock sensitivity. 18 is ok but for a dog that has really thick fur it should be a bit higher even with long leashes my dog still feels it but she is just like yes ok but to solve this problem I will her just shave where they sit, no need to use a shocker every day. but what do i need? I need it to feel I would still recommend them
