Hi
Been using one for two years now. Very happy with performance and at current sale prices, they are a very good value. Best feature - reverse. Dam near impossible to get it stuck with a reverse gear.
Typical outing is drilling 15-20 holes and have never run the battery down past two of the 4 lights. I do keep it inside the shack as cold will reduce battery life, so if you are out on a bucket and leaving the auger outside, you milliage will very.
