I have 2 maltese dogs who tend to get matted hair. I like to cut their hair about 3/4 to an inch in length and was using a cheap 20.00 clipper set. I couldnt get through their hair at all and it was taking me hours to clip them. I was hesistant on spending sooo much money on dog clippers but considering I had 2 dogs and groomers cost 40 bucks a pop, I figured I would give this a shot.These clippers are FANTASTIC. They cut through anything. They also reduced my cutting time on my dogs by about 45 minutes. No more mats getting stuck in the clippers and me pulling at it and my dogs yelping.The ONLY cons are this does NOT come with the black comb clipper guard attachments so if you want to cut your dogs hair different lengths, you need to pick up a set.Ive used them 4 times so far on both dogs which would have cost me 320 bucks in grooming costs. It was a 20 minute drive to the groomer to drop the dogs off and then a 20 minute drive home. I can now cut each dog in 20 minutes with these clippers. They pay for themselves and save you a TON of money and time.December 2012 Update: Still have these and they still work flawlessly! I give my Maltese a good brushing to get all the knots and mats out and these cut very smoothly.
