HURRICANE6 in 1 Folding Nut Driver Set Metric, Hex Nut Driver Set, Folding Socket Wrench, Cr-V Steel Shank, Portable Premium Aluminum Handle. Easy to Carry Out. 5mm, 6mm, 8mm, 9mm, 10mm, 12mm

these nut drivers work well. The unit is well-made and the flexibility of the nut driver positioning is good.

Excellent quality & handy to have when you don't know the exact nut/screw size.

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.

This tool is good to have in your pocket or your professional daily carry tool bag. When you are a service man and you are traveling from place to place, job to job daily , you definitely want to keep your tool bag light. Although this piece of folding tool is a bit heavier and larger than I expected, but it will save you some trip going back and forth to your truck to find a right size of tool to loose 2 nuts. especially when you parked 5 blocks away. I will use any kind of pliers or wrench I can find to loose that nut instead of wasting time to walk back to my truck. A full set of nut driver is a better choice, but do you really want to carry that around? Thanks to the person who invented this folding nut driver, I can now put my adjustable wrench and pliers away (or maybe my leatherman the one and the only a multiple Mcgyver tool)

I bought this primarily for the 1/4" driver, but having the other sizes is a nice feature. Because of the Swiss Army Knife-esque design, I just assumed that this tool was the same size as one of those, but it's much fatter than a standard SWK. The different drivers do not just pop out. It can take some effort to get them out actually, but that ensures that they'll stay steady when in use. Overall a great tool to have on hand. I plan on buying the metric version as well.

This is handy, given that you have several sizes convenient. It's a little bit awkward to use, but ok for occasional use.

Super durable expect to last quite a while
