Allenker 2019 Upgrade Version Dog Bark Collar with Beep Vibration Static Shock - 3 Levels Sensitivity, Rechargeable Bark Collar for Small Dogs Medium Large Dogs with Breathing Light – Rainproof

Works great!

Worked briefly. Will charge does not vibrate or shock. Waste of money. Realized it quit working right after the exchange/ return time was over. Not sure if it is faulty or just bad design.

Within the first week the collar started vibrating my dog when he wasn't even making a noise. Returned

Didn’t really work. Would shock dog when he shook his head.
