Review on Bousnic 2-Dog Training Collar: Upgraded Shock Collar with Remote - 1000ft Range, Rechargeable, 🐶 Waterproof - Beep, Vibration, and Shock Modes for Small, Medium, and Large Dogs (15lbs - 120lbs) by Michelle Larsen

I liked this/these (I bought two) collars for the first week. Setup was easy and the remote control was easy to use. I had a different collar for about two years and found the remote control confusing and difficult to use so I loved it. I was happy until the vibrate function on one of the collars stopped working. I know the collar is properly connected because the horn and shock work and the device lights up when I press the vibrate button on the remote - it doesn't actually vibrate. I will contact the manufacturer and update my review based on how they respond. Check back in a few days for an update. You don't have to wait several days for an update. I emailed Bousnic and they responded almost immediately (and it's 10:30pm EST). They will replace the failed unit. So now I like this training collar again. As I mentioned, I had a different brand collar for about two years. It was difficult to read another brand's transmitter and I often corrected the wrong dog or was shocked if I just wanted to vibrate. Charging other devices was also difficult - charging required detaching the devices from their collars, which was a real hassle. The Bousnic transmitter is mostly legible. Charging is as easy as lifting the silicone case and plugging it in. The only thing I suggest you is to make the buttons for the discharge in a different color. I plan on putting a dab of light colored nail polish on the shock button because if my dog goes into full psychotic mode I can get confused and make a mistake.
