I bought a Used still in the box never had a batteries in it DT Natural Bird Launcher and could not for the life of me get the remote to pair up with the receiver. So I first called them, was talked through it by Ray, could not get it to work. So I sent it in for repair, knowing that it being used, I was going to foot the bill. Now, I will admit their repair service is a bit slow, (Two weeks till they called) but when Ray did look at it, he determined that a button on the side was in the wrong position and it was operator error, and paired it right up. Then he boxed it up, sent it back out at no charger to me. Not even the return UPS shipping. Good service for a used item!!
