Pro- very long distance and wide range of shock resistance. Make sure you adjust to the smallest amount and move up. Can beep, vibrate, and shocks options.Con - the lock/unlock can slide easily. It happens a few time in my pocket.I would recommended this due to it price and features

This thing is awesome just what we needed for our disobedient pooch!

The battery life is really good.

Love this training collar. My dog is a heathen without this collar on. He listens to everything with a quick vibrate and comes on command.

I only had to use the bell sound several times to get my dog’s attention. Now I just say “no bark” and he stops. So worth the investment.

This collar is easy to use. The free extra long sensors/prongs came in handy too. The vibration strength gets my dogs attention.I wish there was an easier way/better instructions to shorten the collar.
