UPDATE: I have returned this product, but it's still a 4* product. I returned this product because of a few reasons. Firstly, it's not quite powerful enough to do the job I bought it for. 60Nm is useful, but not quite beefy enough. Secondly, the on/off action gets irritating with repeated use. I prefer to start slowly and then introduce more speed & force progressively. So, subsequent to buying this tool, I bought the AC Delco ARI2104 3/8" impact wrench, which is more suited to use for tyre changing and raising and lowering my car, but I also bought the ARW1210-4T 1/2" brushless wrench, which has all of the good features I like in this ARW1209 wrench, but adds the extra power I wanted (95Nm) as well as progressive speed control. (I also bought the G12 series ARD12119 drill and the ARW1210-2P 1/4" brushless wrench, which is the baby brother of the ARW1210-4T and gives me the charger I need having returned the ARW1209P-P2). The ARW1209P-P2 is still a great-value tool (make sure you use the promotion), but for my needs and preferences, other tools in the G12 range have made it redundant. Fortunately, Amazon's excellent return policy makes buying these tools risk-free. Original Review: I'll put my hands up and admit I came across this by chance and noticed it was heavily discounted, so I bought it on impulse as I'm a sucker for an Amazon deal. First impressions are excellent, with a chunky, hefty, well-made ratchet body, with batteries and charger that seem equally well-made. The ratchet mechanism itself feels strong, and is simple and effective. It comes with a pretty basic set of sockets, so I also treated myself to a set of deep 3/8" sockets which have proved to be very useful as there's not much clearance between the chunky tool and whatever you're working on with the standard sockets, and when tightening, you can find your hand being jerked a little when you reach the limits of the torque, and then it's sore knuckle time. (See pics) 60Nm torque sounds like a fair bit of grunt, and it is reasonable, but it's not enough to be loosening wheel nuts, which on my car are rated at 120Nm. However this ratchet has a handy feature in that when the motor stops tightening the socket, you can keep going and use the ratchet as a traditional ratchet, albeit a heavy chunky ratchet. It works excellently and intuitively; the motor stops and you just carry on using it as a normal ratchet. In a rare moment of genius, a while ago I bought a car scissor jack that would accept a 17mm spanner/socket. It came with a cheapo ratchet but I found the ratchet a bit short to make life easy when jacking my car. This electric ratchet makes jacking up my car much quicker and easier, though I noticed while it jacked my car up fully on most occasions, for one jacking point, it stopped, and I had to finish jacking up the car by hand. This was no great hardship as it was pretty much there already. Then I could use the ratchet as a quick way to remove wheel nuts once they had been loosened from full tightness first. It really does feel like cheating when I whizz the jack up and down with no effort, compared to the normal faffing around with a scissor jack. If you register your ratchet within 30 days of purchase, you get an extended warranty covering you for 2 years, which is pretty reasonable. I really like this ratchet. It makes working on my car a bit faster, because it works pretty quickly, far quicker than by hand, and the ability to double the torque applied by treating it as a normal ratchet spanner is genuinely handy. But hand on heart, I'm not sure it's worth the £95 for the two battery pack set. But the good news is that I'm not convinced two batteries are necessary for most people. It's not an impact driver, and it hasn't quite got the oomph that's needed for working on cars, so for proper mechanics, I can see them scoffing at it and using a proper air-powered impact driver. That said, for lazy occasional DIYers like me, it's pretty nifty. I can see me using it to make jacking my car up easy and convenient, as well as removing my wheels (normally for detailing) that bit quicker. The fact that I will be using it regularly tells me it's genuinely useful, and not just some gadget that's not worth the space it takes up. I can also see it being useful for other jobs, where the low torque output is less of an issue. (Self-assembly furniture springs to mind.) If you fancy an electric ratchet, then this is a pretty decent example, especially if you can snag a deal on the two battery kit. But even if you can't, one battery lasts plenty long enough and if you're that serious about needing to speed up working on cars, get the proper kit. This electric ratchet is hard to justify as a necessity, but as a handy luxury, go for it!
