I bought one of the Clarke 18v battery powered ones and wasn’t impressed. Took it back shortly after buying it and got a refund. Seems to be a popular buy and a lot of people rate them, maybe mine was duff?
Out of the packet it was OK, in the space of a week it just went down hill – batteries were near enough useless and would die after a few attempts (I am a nerd so conditional all my rechargeable batteries). Despite claiming 150lbs/ft it wouldn’t undo my wheel nuts (90lbs/ft) and when I did some tests would only crack 50lbs/ft with a full charge, and that dropped after a few uses. The only nuts I successfully managed to undo with the gun was the top mount bolts on the Golf (not tight just a captive arrangement) – for everything else it was rubbish. Also couldn’t tighten anything up either – finger tight at best!
I got myself one from maplins, for £11. It's wierd - Runs off the ciggy lighter/battery and sort of spins up to speed and then BANG, one really solid jolt every 2 seconds or so.
It handles very very tight wheels in 4 jolts, and seems to be lasting OK.
It also got me out of a bind with the strut top nuts that you need an impact gun to get off (the hex recesses just rounded off straight away when holding the damper shaft with an allen key, but the impact jobbie got them straight out)
My mate has a makita impact driver, not really a proper mega heavy duty thing. It makes some jobs quicker but it's not got a lot of guts.
Another mate has a snap on (iirc) impact gun, and it's pretty good. Not quite as good as an air wrench though, and I recall it being expensive.
it's lasted a year, and had the wheels on and of dozens of times. A lot faster than doing them by hand. Doesn't show any signs of packing in, but it wouldn't really want to use it for more than occasional jobs.
I had one like the Maplins one a few years ago accept Woolworths (RIP) were selling them for £15. A bunch of us got them but after a few drift days and a few scrapped cars the dog engagement inside wore out on all of them. They are cheap though
I've got a Snap On 18v impact wrench & it's awesome (this one) It came with 2 batteries (spare always charges before I can run the first one down) and is rated at 400lbs/ft (I haven't defeated it yet..)
It's *probably* as good as they get BUT is almost certainly as expensive as they get too ;D

I've got one of the cheap 12v corded versions and have stripped down numerous cars with it. Recently I bought a proper cordless impact wrench and am a convert. Not a high powered unit so I still have to crack tight fasteners with a power bar but a useful tool to have. Next time I will get a high powered version but at present the lower powered has proved how good they are - expecially if like me you have problem with your hand strength.
They are ok, but whatever you do don't rely on them for torquing up the bolts, make sure you check they are tight manually.IMO they don't last too long, you are better of getting the cordless one if your going to use it often.
I have a Clarke Corded one that either attaches to the battery or plugs into the ciggy lighter. It works really well. Made mince meat of the rusted suspension bolts on my Bro's golf and I think it was about £13!
