Heavy duty tool for light work! GREAT VALUE IMHO
Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set, Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set
Great tool to add to the box. I had this in my cart as I was looking for something small that was electric and had a flexible head, mostly for auto (being able to get all but the torque in tight spaces) and also at work where I’m constantly using a driver and wanted to save my wrists some work. There are others out there, but most are Amazon only brands, which come from China and are hard to get good customer service if there’s an issue. You buy something and have an issue a year later and find that the company either doesn’t exist or has changed their name. It’s a tactic. I buy USA made when it’s available, and buy American brands like Skil and Craftsman, etc. as you can trust they’ll make things right if needed. Anyway, I love this thing. I use it multiple times a day, but it’s about 6 bolts in, work for a few hours, 6 bolts out, then back in, and so on. So I’m not running it non stop. It’s a $20-30 tool, so I don’t expect it to last with some crazy heavy use on a job site. I don’t use the bit it came with. I use this exclusively with socket driver bits. Mostly a 1/2” tool get the light work done, then pull out the torque wrench and finish it. I saw this on sale in town for the same price, so I bought one for my 17yo son who is always wrenching on stuff. Great tool to have for getting the lighter thousand turns out of the way. It would probably last forever if used around the house and charged by the book. I’ve only recharged it once and at the rate I use it one charge lasted a couple weeks. It is built very well, and has heavy-duty rubberized grip around with the body of a thicker, power tool type plastic. 100% recommended to anyone and everyone. This is the type of thing any man that actually works and fixes things around the house and garage/shop, young or old, would appreciate.

Decent driver, but no real torque control
Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set
As others have noted, this driver works well overall, but would be better if the head could go to 90° instead of just 45°, and it comes in an extremely hard to open package. I'd like to point out a couple of other things that I haven't seen mentioned.
First, although this tool claims to have torque control via the three-level setting on the handle, it's not like most drills and drivers. With them, when the maximum torque setting is reached, a clutch disengages and the tool just 'freewheels.' But this Skil driver runs until the motor stalls, and its three settings merely control when that happens. In practical terms, that means the tool can wrench your wrist pretty badly. Even at the lowest setting the torque is considerable, making it all too easy to strip threads or even break off screw heads. This also makes it more likely to injure your wrist.
Also, in case it wasn't obvious, this tool's battery is not user-replaceable. If it runs out of power in the middle of a job... too bad. And when eventually it gets to the point where it will no longer hold a charge, Skil's only suggestion is to "Have the tool serviced by an Authorized SKIL Service Station." If you can find one, that is. If you don't want a disposable tool, this is probably not for you.
Don't get me wrong--I like this driver, and it has already come in handy in a few situations where my regular drill/driver would have been too bulky to fit. But it's good to know its limitations.
Skil also makes a smaller, less expensive 4 V screwdriver that lacks the adjustable-angle head of this one. If a straight power screwdriver is all you need, that one is worth considering:

Trendy shirt and great price
Great shirt and great quality! My son loves it and gets lots of compliments. It’s a soft, nice material and true to size. I’ll be ordering from this seller again.
