Review on 🐶 Extra Free Spirit Remote Trainer Add-A-Dog Collar - Enhanced Tone, Vibrate, and Shock Features for Improved Training by Angela Smith

My last dog fencing system was about 20 years old and I repaired the collars myself. Alternative and found this brand. The features look good - I really like the vibrate/sound setting - it will stop the dog in its tracks. My first order of the system and additional color - one collar didn't work at all and the other didn't make any noise when it was supposed to. So I contacted Revain and they sent me a replacement. First replacement I tried the collar - it works. Vibration and noise are exactly as expected. But I tried another collar and nothing - exactly the same as one of the collars from the first batch. The collars are well made and good value so I think it will be a godsend - I will try Revain again and hopefully end up with two working collars. Companies need to improve quality control. But because of the cost - I'll try a few more times. To update. I think my extra collars are for the distance learning system, not the fence. Apparently I ordered the wrong ones. Work on finding the right one. Maybe just one of my two devices was not working properly.
