I have owned a well known brand power gun which cost 3 times as much & I can say this is much better than, it’s more balanced when using and is very powerful, really good One technology adjust speed and setting through a app, Geofence technology which means if the tool goes missing it will inform you

Great bit of kit, has undone car bolts with ease. Absolutely love the ability to change settings via the app too. One moan is why is the case so flimsy and cheap feeling - you'd have thought an expensive bit of kit would come with a sturdy case

Fancied one for a while, got tempted when they were on offer and combined with toolstation club discount code it was an excellent price.

Settings great for lowering torque and increasing for plenty of power.

Only downside it it’s a touch heavy but would definitely buy another for the right job it’s excellent

Great deal cheapest i could find and very convenie

what can you say - its Milwaukee! - seriously tho' - does what it says! But....! -but...... be careful, doesn't need to be on the highest setting for car wheel nuts (as I found to my cost) - it just stripped an anti-theft locking nut.... (my fault - not the tool)

abc reviews Verified Purchase

Had read several reviews of this wrench before buying, so that side was a given. Checked on line and Toolstation was the cheapest "shop" where you could go and buy it. Don't trust online only stores, prefer a shop front and a person. Very happy with Item and purchase experience.
Have to say that instruction manuals and details of extended warranty were very poor in the first instance, and non existent in the second. The shop assistant told me about the extended warranty, or I would never have known. I also could not get the app to recognise the kits bar code or QR code, so consequntially is not linked with the app. For me that's a minor point.
