I am writing this after using the Gun Dog Training Collar T850 for only two days. It has a sleek design and is not cumbersome for my dog. The three modes; Sound (beep), Vibration, and Static makes it a viable training tool. I have used the Sound mode the most since it allows me to change behavior with the least amount of input from the collar. I have only used the vibration mode once and it was so effective that I may never have to use the Static mode. Charging was quick on both the remote control and the receiver. I like that it has the silicone cover for the receiver electrodes to ensure no harm to my dog in case the Static mode was inadvertently used. Excellent product! I would definitely recommend it to my friends and families.
