After alot of looking around, and being in the steel erection and auto trades, i decided on a
- Mac Allister 14.4v 1/2" impact driver for £90ish at B&Q in 8-08, rated to 176nm, 2 batterys and hour charger, 3years warrentee
With full battery it would undo 210nm, tighten up to 200nm,
1/2 used battery undo 195nm and do up to 190nm,
3/4 battery used = 175nm undo and do up to 165nm
And the batterys last really well. even tho now they are 2 years old.

I use mine for all my vehicle needs, plus for work (nut running up to m20 bolts, but does need to be loosened off if real TIGHT, and also torqued up as quicker and dont put OTT strain on the gun (air line torque gun is for the bitch tight bolts), also with the adapter that come with it, 1/4" fitting can be use for screws etc for building trade usage.


Comparisons,
- After over a year of back to back usage along side 18volt 1/2'' DC822 Dewalt (£270 with 2xbatterys and charger, or £160 for just gun) i used to have at work it, it was evens on performance, just the dewalts batterys might last alittle more, (well it was a 18volt)
- Seems alot better than Clark's etc, lighter, smaller and great power.
- Also used it against my mates 18v and 24v Snap-on guns, not sure about Snap-ons battery life, but mine wont undo real tight bolts like the snap-ons, but mine is about half the wieght and size, and fraction of the cost.


I have returned mine once, as it failed in the 1st year, but that was more to me undoing every thing with it (now i slacken the real tight ones off 1st, rather than let the gun attempt it for 30+ seconds, i also put up aload of plasterboarding, which i think the dust is what caused it to fail, as it was whilst and after 3 days of plasterboarding that it the trigger started to play up, then failed.
2 years since ive had a replacement the guns been good as gold, and it gets used alot.
