Review on 🐶 Rechargeable Remote Control Mini Training Collar for Small Dogs 5-15lbs - Waterproof & 1000-Foot Range - Beeping Sound & Vibration Mode - Adjustable Strap 6 to 26-Inch by Brenda Hobbs

This little thing is powerful at close range. I was very skeptical at first as it only vibrates and beeps, but it's super efficient! At first I thought it really stuck to my dog, but then I tested it on myself and it just vibrates. I recommend 10/10. The only comment is the rivets. The spikes are usually designed to come into contact with the skin in the event of an electric shock. However, since this collar doesn't really shock, pointing the spikes outward is pointless. In this case the pins are only used to hold the device instead of the actual collar. Why not install a flat head stud, screw or nut? Just a recommendation for future engineers if this product.
