2 in 1 Dog Training Collar Automatic Anti Bark Control with Remote Rechargeable and Waterproof for 3 dogs

The collar arrived promptly and very nicely packaged. It was easy to charge and actually holds its charge longer than expected, which is great. I have the audio set to its lowest beep, and so far, that has been all it takes to get my dog to stop what he's doing and listen to my command, behave (and get a treat). I think it can be a very valuable training aid for many pet owners!
