If you have tried to clip your dog with a cheap human hair clipper you know they do not work. This clipper is specially made for double-coated dog breeds. The run was very cool and quiet. This is a new and never used product. The box looked like it was opened because it was. I opened it to make sure all the parts were there, and it charged and ran. • Stainless Steel Blade • Powerful Rotary Motor • Long-life Lithium-ion Power • Cool, Low Noise • On/Off Switch • LED Charging Light • 5 Adjustable Cutting Positions • Cord/Cordless (allows freedom of movement), Full Charged 90-minute Runtime. • Includes 4 Comb Attachments (1/4", 3/8", 1/2", 3/4"), Lubricating Oil, Cleaning Brush, and Instruction Booklet
