As described, I have 6 of them so far and they work perfectly.

EXCELLENT²! I really liked it! Easy to set up the fence. It far exceeded my expectations. My dogs are "FREE" now.

I haven't tried them yet but they look very good, they arrived very well packaged, as soon as I try them I will write again.

Well packaged. Fast delivery. Very positive, just as advertised.

Nice, you place yourself in the center of the perimeter, press the GPS, and it remembers the location. It's easy to use and works very well.

Dog collar is accurate it works under our leilani trees they have tick foliage. Got 2 of them and both a very good but one measures in feet and the other in metres not sure if there is a setting to change from feet to metres, but thanks to google for balancing out the measurements .

After putting on the collar, the dog decided to run out of the property. He disappeared, but in 3 minutes he found his way back to the kennel. Now we go for walks together and teach him to stay within the allowed area. The device works great for me from the first use.

This is the second one I've bought. Since the other one turned out really good.

IT WORKS VERY WELL. WITH THE BEEPERS IT DOESN'T DARE TO ADVANCE. I WILL BUY ANOTHER ONE FOR THE COLLEAGUE.

Hello, I tested it on myself, everything works fine.

Very effective for the dog to learn the boundaries of the area and I don't know what to say anymore.

Excellent. dog picked up the boundary warning on their own and returned to the safety zone on the first try

It works excellent, the only detail is the battery life.
approximate duration: 3 days

A good collar, the beep is a bit loud, it takes 2-3 minutes for the collar to detect the GPS, easy to use even in English.
It takes a few training sessions for the dog to understand.

Works very accurate, battery 3-4 days. quality 9/10

For the price, this is a surprisingly good unit. it works as intended, the sound and vibration strengths are very good,,, i didn't personally grab the probes to check the zap strength, but i assume it'll be just as potent as the other strengths are. it connects up quite quickly to gps, like about 1 minute on average. it will lose signal by going under metal roofs, so that's something to consider.

Honestly, the necklace is great. direct dog training. central position plus freedom of movement. My dog stays at home now.
I highly recommend it. (and no subscription)

It works quite well, the dog learned it right away.

Seems to work great

For now, it seems to be working.

Easy to use and totally effective! My dog stays within the boundary!

It's the second one I've bought, and although the battery only lasts 1 day, we are satisfied.

Great product, no need to fence my property.

Very satisfied, I recommend.

A good fencing system, works very well in field, but poorly near woods. Over all training dog with it is perfect.
