Bests & Worsts Reviews from Amazon

I work for an Oilfield Service and Hotshot company in North Dakota. Though I purchased it from Menards and not Amazon, I thought I'd weigh in with my two cents. I have used it to raise dump trailers full of gravel, jump tractors, start my generator when the power was out, start a Freightliner truck, run a 12 volt heater to thaw my snowblower, jump start my Polaris Ranger and to charge my phones. I've never had a problem with it. I charge it once a month and plug it in for a couple hours after a heavy use. I store it inside to prevent continued exposure to extreme cold and it works great. I recommend it.
