I have one and love it. There has been a pretty lengthy post on this already. But just to answer the weight question...yeah it is heavy. I weigh about 180 or so at 6' tall. By no means in "great shape" though. I just punched 12 holes solo after work and lugged it around in a 25-40 yard radius. Is it a work out? yeah. Possible? for sure. It is tiring, but I dint work out or anything either. It's actually a nice workout for me.
We drive out on the ice this time of year, but even when i pulled it in a sled, it wasn't that big of a deal.
No issues at all so far. Still on my 1st 1# tank and I have to have darn near 65 holes in 12-18inches of ice at this point.
I would reccommend it to anyone. I love it. I just started though and never owned a gas Auger either, but i didn't want to have to deal with anything. It's sweet.
