This is an interesting collection of metric nut-drivers, packaged like compact Allen-wrench collections. The set is bigger than I was expecting, but once in your hand, you realize it couldn't be much smaller. The drivers and spacers are steel, the sides are anodized aluminum alloy, with adjustable bolts to control the force needed to swing a nut-driver in/out. The set weighs just over 3/4 lbs; that's a little large/heavy to carry around all day in my pants pocket, but maybe not yours. Opened 90°, the handle will provide a huge amount of leverage (maybe too much if you're not careful), opened 180° the leverage is more like what you'd get with a conventional nut-driver. In either instance, the unit is more ungainly to work with than a set of individual nut-drivers, but the advantage is you're not wasting time rummaging around in the tool drawer looking for that hidden 9mm driver. In summary, this is a great one-off tool -- perfect when you only have one or two nuts to remove/install and you need multiple sizes. But when you have a dozen, you're better off using a regular nut-driver.The product description says drop-forged sockets and chrome vanadium shafts. Two materials implies excess torque could separate the socket from the shaft, especially with the handle opened 90°. I didn't try to force that failure, and given the socket sizes it seems unlikely you'd need to be applying that much torque. Nonetheless, it's something to keep in mind. That's not meant as a tool criticism but an operator warning.

I was surprised that the body is metal, most things like this at this price these days have "really tough plastic" (sarcasm here) for a body. This thing is solid metal. My only complaint is the most common sockets have shorter shafts than the other, smaller less popular sizes. 10mm as opposed to 9mm.

This little tool saves a lot of time when you need one of these Metric sizes to work on something like Lawn Mowers and Washers and Dryer`s.

It's a little big, but necessary to have the size selection. Very sturdy and appears well made. Easy to use.

In terms of sturdiness it’s good but it can’t be used in all places.
