Cordless impact wrenches - cheap vs expensive

I'm going to get a cordless impact for changing tires at the track. Anyone had both a cheap one and a nice one want to describe the differences to me? I don't have a problem with spending $200 on one if it is noticeably superior to a $50 one, but if I won't notice any difference, then I see no reason to spend the extra money.

I got one from Harbor freight a couple years ago. I think it was $80 or so. IIRC it was supposedly 140 ft/lbs but in actuality, it's nothing close. Still very useful when I go AutoX'ing, but sometimes I'd have to break a few lugs looks on my own with a tire iron.

I think I have used and evaluated every cordless impact made for work since we use quite a few on the assembly line. This is what we use alot of of and what I have at home. Probably the best price-power-weight-size of any cordless out there. 3.5 lbs with battery and puts out an honest 160 ft-lbs as tested at work on our impact tester. There are stronger ones out there for sure, but they either cost more, weigh more, or both.

Cheap ones have crappy batteries that don't last and put out way less than advertised torque.

Never had an expensive one but I've had one of those older orange Harbor Freight ones for about 5 years now. Still works great for lugs and most stuff short of 100lbs. I always hand brake lugs loose anyway to save on the wrench and lug corners. The pinion gears inside were a weak point but HF is good about providing service parts for all their stuff.

I had a cheap one, made by Cummins Power Tools, supposedly 350lb-ft, cost about $100. It worked fine, but only had enough power to take off lugnuts and that's about it. In reality it was good for about 100lb-ft tops, I'd say. Similar my experience with Harbor Freight impact and a Craftsman one (reliable, but not that powerful)....

I have an older-model Snap-on impact now (bought used for about $200, new they're about $400) and it is "rated" for 400lb-ft IIRC, and I would think it comes fairly close. Anyhow, it will undo ANY bolt, anytime, any place. It's taken off rusted main hub nuts, big rusty chassis bolts on the jeep, and makes quick work of taking off lugnuts. Battery power is good (I have 2) and the charger is fast. It has been used hundreds of times and still works great...been abused, dropped, used as a hammer a few times , etc.

The moral: buy a really good one (Snap-On is the best, IMO) once, or buy a few cheap ones until you figure out they can't do what you want them to do and end up buying a good one later.

One of the few things where you get what you pay for!

btw, I own Jason's old 3850 and it has never failed me. I am positive it has over 250, since it has undone things that my 175lbs on the end of a 4' cheater pipe could not undo.....
