Query: PLEASE!!! Don't throw your money away!!!!!!

This is absolutely the biggest piece of junk that I have EVER thrown money at!! This thing eats batteries every two days (whether I turn it off when my dogs come in or not!)!! I have spent more money on batteries in two months then I did on the original item AND I am not even using the shock function, just the noise!!! PLEASE, PLEASE, PLEASE save your money and your sanity!!
