I've had the 8" auger about a month now and have had the opportunity to drill a couple of hundred holes ( lately thru about a foot of ice).
Pros: It's very light(17 lbs), it's quiet, it runs smooth, it cuts a clean hole, it requires no downward force at all(it's shaving the ice), the engine and controls are boxed in the handles for protection and can be laid down on any side, it runs on a 50:1 mixture, the gas tank has a vent/tube filter so it is always vented and it can be converted to a hand auger in about two minutes.
Cons: the price, it takes a good two minutes to warm up, it is very tall, it doesn't have replaceable or resharpenable blades-you have to buy a new head(about $40) but it should last for years, lack of carb. adjustment screws and no primer bulb.
After using this auger I can honestly say it isn't a "TOY" as I've heard it refered to as. The same people who refered to it as a toy tried it and were amazed by how it cut and how light it was. It gets the job done in a timely fashion and losing that 10+ lbs is great on the back !
