Review on 🐶 CNHUALAI Rainproof Dog Training Collar with Remote - Shock, Beep, Vibration - 2 Dogs, 2 Receivers - Rechargeable, Waterproof - 1~100 Levels Training Set for Dogs by Tamika Martin

This shock collar works very well for the price. I've had more expensive collars in the past (the high price hasn't kept them from breaking over time) that are better built, but this collar also has a few features that I like. This collar gives you the option of using two collars. directly from a remote control. This is useful when training 2 dogs, but I like to use a second collar as a backup in case one fails. The remote control is also rechargeable - no need to worry about the battery. The charger can be plugged into the USB port, which is convenient when you need to charge it in the car. Collars have a beep function - in most cases, a warning beep is enough to make my dog reconsider his annoying behavior. . The volume is not adjustable. It's not as loud as other collars I've used, but loud enough to get your dog's attention. If the sound signal is not enough, the next step is to vibrate the collars. Both vibration and shock are adjustable from 1 to 100, which feels a bit overkill. It seems like they might as well make it a 1-10 dial as there isn't much of a difference between 10, 11, 12, etc. I tested the beats on myself to see the different levels. A backlight suitable for use in sub-optimal lighting conditions. The collars are waterproof, making them suitable for hunting dogs that may need to be pulled out of the water. Great option for the price.
