Review on 🐶 WILLBEST 2021 Upgraded Waterproof and Rechargeable Dog Training Collar with 1650 Ft Range - Beep, Vibration, Shock, Tracking Light Modes by David Kits

Just arrived. Yes, it has an insert for a loose third collar. Let's see how fast it arrives. The first impression is very positive. The controller is quite small, the buttons are comfortable. The volume is fixed, but the intensity of the vibration and stimulation can be adjusted from 0 (none) to 99. In addition, each of the two levels can be controlled separately and set differently for each dog (6 unique settings in total). The LED shines brightly at dusk or at night to locate dogs. I'm only giving it four stars because I haven't used it enough for five stars yet. I will update after the third collar arrives.
