We use Wahl Lith Ion ProSeries Pet Clipper. It is pretty good but definatly not professional quality. It gets the job done and way better than the old cord one that we had. It takes a few hours to get our two trimmed, but they are on the bigger side at 10 and 11 lbs. But I say as long as you have the time and patience go for it. I do not have and extra $100+ laying around for them to get trimmed every month or two, so the cost was definatly worth it at $55. Start young so they get used to it. Our boys get better every time we cut them
