so far so good!!! Yoda is responding very well with it. I have to buy different treats or else he may get burned out on the ones that I have. I didn't do it the way the pack that it came in suggested, BUT I will say I will not "clicked" it if I do not have a treat handy and I only use it for the positive, not when he does something wrong (like have an accident). So I am going to give it a big thumbs up!
