Absolutely excellent. I'm a fairly picky person and expect that in today's technological times we can produce products that work and function properly. This product has been outstanding! Excellent quality, great range, very flexible and most importantly: it works!!!
Charge it up, attach it onto the dogs existing collar or use the collar provided. The electrodes do not have to jam into the dogs neck, we attached it quite loose. Now get this: my dog entirely responded to the vibrate mode alone, I never needed to use the shock feature! In less then 3 days my dog stopped running outside our gates and into the street.
Someone asked me "how much did that cost?"...and my reply was "it's not how much it cost, it's how much it saved....at the most, it may have saved the dogs life, our kids being freaked by a hit dog and at the very least hundreds of dollars of vet bills"
True story: at night I open our front gates as I walk out to our mailbox to put some paperwork in it (my crews pick-up the paperwork each morning). Our dog usually bolts past me and runs right across the street to sniff and what-not...she always runs past me and I'd yell and try to stop her...she just did her thing. After a few buzz-vibrates she no longer does this. Last night I went out to put stuff in the mailbox....as I approached our gate our dog started to run towards me, I also noticed a mini-van coming down the street at a very fast rate...had the dog bolted past me, it would have been a perfect collision; all I had to do was say "wait" and our dog stopped and did not run out into the street. As the speeding mini-van passed (at excessive speed). I noticed a teenager laying on top of the roof grabbing onto the roof rack! Just some High School kids goofing off....but just imagine my dog having run right out in front of that mini-van...hard brakes, maybe a swerve, potential loss of control...and what about the dumb-ass kid laying on top? Yeah, pretty ugly. It never happened, and this device is what curbed that behavior. Definnitely 5-stars!
