Electronic Training Collar for Dogs with Remote Control - Shock & Bark Collar for Small, Medium and Large Dogs | Waterproof & Rechargeable E-Collars | Pet Obedience Trainer & Correction Device

This thing is a great value for the money. Works amazing for our dog and very easy to use.

WARNING: The power will change between uses!! I’ll shock them, and however long later that I reuse it, the power will be on like 89 or even 100 (it works perfectly for my dogs at only 5). BE CAREFUL.Otherwise works as intended! I have 2 German Shepherds and it works perfectly (other than the above). It would be 5 stars except that’s a huge safety issue.

Works fine but doesn't seem to hold a charge very long. Have to plug it in every two or three days even though we only have to use it for our puppy once or twice each day. Other than that, I'm very pleased.

Great product, will buy again!
