I have used this collar for years with no issues. With the proper training they are a great tool.

The collar works well to keep my dog home without a physical fence

We have an escape artist who can climb over fences.
The collar stopped this. Now, Coop keeps a healthy distance from the fence. THANK YOU!!!!

Keeps my beautiful, stubborn dogs on our property. Now if I could just keep the strays OUT of the yard.....

I am very happy because now Rufus is safe running around in the yard

GOT HERE AS PROMISED AND IS WORKING GREAT

It is Great

Great for dogs that can no longer hear the tones. Tone is first, vibration second and then the 'tingle'. it's a little heavy, but works great.

After losing our female scottie in a vehicular accident outside our home, we purchased one of the RF-275 as a test and put it on our our male scottie (yes he is above 30 lbs) and have set it on level 2. The RF-275 has worked perfectly for our little boy. The added feature of vibration has really kept him away from the boundary lines. The fact that it is water proof is a great plus as he has found that jumping into the koi pond is great fun. Great product A++

my Australian shepherd is very stubborn, he has figured out how to cross the fence to get out ,but 90% of the time he won't cross back into yard without removing collar.
