I GOT ONE! I GOT ONE!! love LOVE LOVE IT!!! i HAVE THIS BRAND--THIS EXACT BOX---> It costs $20. You must MUST MUST follow the step by step directions on how to introduce this to your dog. YOu can NOT just buy one and bring it home and go to town on your dogs toes, he will HATE IT. BUT-------I followed each and every step, it takes several days, and my dog has NO problem with it, actually, when he sees the box come out, he FOLLOWS me, cuz he thinks: that item = TREATS for ME!! I did initially have some problems with it. AT FIRST, I WAS SO DISAPPOINTED....... until i got some advice on a new way to use it. from a member here on DTA. The instructions say do not grind on a nail for longer than 3 seconds, or "the nail will overheat". well, at 3 seconds per pass, it takes all evening long to trim the nails down. Someone later told me, "No one really does that 3 second thing." So i tried it, grinding away for as long as it took. I could NOT detect any warmth whatsoever, and my dog seemed perfectly comfortable. YOUR dog might only be able to tolerate 3 seconds per nail at a time, but, my dog can take it a long time, maybe a minute or two or three. Honestly, i've never really timed it. Other problem---I'M LEFTHANDED. This is SOoo designed for right handers. Hard to explain, but there is a lil groove in the orange cap to put their nail in. A left hander can't do it. A pal told me, "No one really leaves that orange cap, try it without orange cap on." Well, the instructions say, like 80 times, in a 36 point font--NEVER TAKE OFF ORANGE CAP EVER, YOU COULD HURT YOUR DOG, etc etc etc. But because i so trusted this pal, i did indeed try it once, with orange cap OFF. WOW----WAY WAY EASIER TO USE!! WHEW!! Withthe orange cap OFF, you can SEE and angle around the nail way way easier. But, with orange cap OFF, I AM excessively careful to make sure all his foot fur is held back, and that i stay away from his paw pads. <----It is NOT hard to do either. I used to slip a panty hose foot (cut off of panty hose) with holes punched into it.........and slip THAT over his paw, TO HOLD HIS PAW FUR OUTA THE WAY.........and only have his nail stick out the lil hole. but, overtime, i decided that was too much bother, and not really necessary. SO IN SUMMARY------- ---I LOVE LOVE LOVE THIS TOOL!!! TWO THUMBS UP!!! BUT do take off orange cap, you can do a better job without it, and do not be afraid to try going way longer than the "3 seconds" the box recommends. I do one paw, play with him, give him a break. He gets 1 tiny treat after each nail. then I do his other paw, and play with him. His two front paws take me about 20 minutes i guess. The next evening, I do the back paws, which never need that much of a trim.
