excellent product. I was having trouble with our male mastiff puppy at 150 I can not manhandle him. I have used training collars before with good results, but the costs are too high for our set income. OS.Com had this on sale so I picked up the 2 collar set . The charge has lasted 8 days and is recharging as I am typing this. I have only had to use the vibrate twice and if he does not do the command on the first request, I repeat and give him a low vibrate and he obey's. Now I just have to show him the hand transmitter and he obey pronto. With the recharge feature it is so cost effect. This is not a toy and should not be overused, it will confuse and hurt the dog or cat. This was a last resort for me because of his size only.
I picked this up for my little dog because I walk her her and an 80 pounder together. He tends to walk more quickly and the longer leash for her really helps her form getting pulled at the neck, giving distance to have me stop him and wait for her before comping close to yanking on her. I have nothing negative to say but I would not buy it for my big dog because he takes the leash in his mouth and tugs at us when we first walk him and experience has taught me that with his jaw/teeth, this would be bitten through in one walk.
