Great product. I used it a day ago to drill six holes in ten inch ice. Blades are sharp, instructions are fairly easy to follow. Two things: no one told me that the eight inch would be so tough on my drill. I am using a new DeWalt XR but it doesn't have enough torque. I know they make one, but mine is not it. The blades bite into the ice and my drill just stops. Then I have to let off the trigger, lift the auger a bit and start again. I can feel the drill heating up. So if you get this get a big drill to go with it. Secondly, I wish it came with a hand crank attachment, or at least that the company offered a hand crank attachment, in case my batteries or my drill fails.
