I was skeptical at first because I've tried two other training collars before. After about a week of consistent use, my German Shepherd started responding to the vibration setting alone. The battery life has also been better than expected.
My dog would bark at every noise outside. The beep function got his attention immediately and we've seen a huge improvement. I rarely need anything beyond the sound mode.
This is my first training collar and setup was surprisingly simple. The instructions were easy to follow and the remote buttons are clearly labeled.
We have a fairly large backyard and the signal has been reliable everywhere I've tested it. No issues with connection so far.
I've only charged it once since receiving it almost three weeks ago. For daily training sessions, that's impressive.
