Waterproof Dog Training Collar with Wireless Remote Rechargeable 300M

Great training collar!My 11 pounds dog has the terrible habit of barking at the yard when some strangers came by. This is very annoying me so I bought this collar to try to stop him. This collar has 500 yards training range and I am very satisfied with that because I have a big yard. I train my dog only use the dual vibration feature that is enough to guide my dog , after one week using the collar my dog is rarely to bark. Also, I can charge the collar and the remote same time and only use one cord. I feel lucky to buy this collar!
