PetSpy M686 Premium Dog Training Shock Collar, 1100 Yards, Medium to Large Dogs, with Vibration, Electric Shock and Beep, Waterproof, Remote Trainer (M686 Extra Receiver Collar)

No strong enough

Like these collars. They’ve lasted years and can get replacement parts if necessary.

We live on a huge piece of land and needed a collar that could be used to train our puppy not to chase the farm animals and work at a distance. This has an incredible range, works even if our pup has been splashing in the lake. The battery lasts 2 full days, allowing us to charge at night and then get 2 days of use. We use the beep feature to find him if he is in the tall grass or far off and now he has learned the beep means we want him to come and he will come running. We could not have calm cohabitation between our dog and the farm animals without this collar, it's a life saver.

I really like these training collars except the on/off button has failed now on 2 and I have had to order replacements. Wish the buttons were more heavy duty.

I originally purchased a kit including the training collar and remote controller. This current purchase is for the collar only, as a replacement to the original collar. After using the original collar up to 6 times per day for over a year and a half, the battery began to be slow to charge. I think that's amazing life for a rechargeable battery! Even when using multiple times per day, I only need to charge the unit once every 6 weeks or more. After the original purchase, my dog was very easily trained to respond to the beep, and when I really need to get his attention I jump up to vibrate. In over a year and a half, I have only used the shock function 3 times, when I worried my good boy was in danger of chasing a squirrel in the road. This has been the most valuable and effective dog training tool I have ever owned.

I don’t usually write reviews, but since I was once lost in a sea of information and training products, I figured I would save at least the few people that read this a little time. This is a FANTASTIC product. I originally bought the remote and receiver to replace a system I had been using, but lost the remote in the woods, (different manufacturer didn’t sell just the remote). I was looking for a product that could go in water and had a decent range AND that I could replace whichever component I needed when my next mishap occurs. I have had zero problems with range or holding charge or button functions for about a year now. I recently added a second dog so time for a second receiver. I watched a video online which showed me how to do this and in seconds the new pupper was online! I can’t say enough how easy this system is to use. SAFETY is my biggest concern and I trail ride miles and miles with my dogs. This product helps me keep them safe and gives me peace of mind when I take them with me. Also, I will probably order another remote just so I have a backup : )

One of our dogs slips her collars - so having another is nice. Secure them well. That's my only admonishment. They are orange and bright - but I have looked diligently and never found her lost collars. Someday I may. (Our property is large and she is smart.)

when dogs have collars on, they behave and there is really no need to even use the remote. But it does work really well when necessary.
