I absolutely love this set up. I run the 1200 ft lb, and a 5” lazer, most of the time. Sometimes I’ll run tye 6” lazer. I have easily drilled 20-30 holes in a day, 5-8” of ice, and Havnt had to change batteries. I use 5 ah batterie. I just use an adapter and it cuts like butter. It’s pretty light, and easy to get out, and even easy to switch auger sizes, which I really like, although I don’t have to often.
I have had this setup a few years, and use it a lot every year. I have had 0 problems.
