Review on 🐶 DOG CARE TC05 Rechargeable Waterproof Dog Training Collar Receiver: Adjustable for Dogs 15lbs-100lbs (Remote Sold Separately) by Ali Anjani

They only get a good review because they give you a five star paid review. Don't waste your time with this garbage! It works great for a couple of days and then doesn't hold a charge and every time you turn it on it has to be paired with the remote. I tried 5 collars in less than 6 weeks and each had the same issue. They no longer hold a charge and will not remain paired with the remote control. The seller sent several replacement units, but after a few days they all became obsolete. You should just be honest and call them a 3 day collar.
