Nice set but there are some trade offs
Upon receiving the Justech Hex Keys Set set I was a little confused by the packaging choice, the set comes in a box with the keys sets each in their packaging and the storage bag in a plastic bag but the wrenches/spanners are just kinda left to float about.
I got the keys out and had and used them to disassemble a desk as a test. The keys themselves feel sturdy and at no point did I feel like they would bend or break, I haven’t used any of the tiny ones yet though. The handle is a very nice addition, I have never used a handle like this before and it really does help add grip and leverage to the keys, this is very handy for these particularly as the finish if not the nicest. looking at them now there are quite a few nicks and scratches in the finish, this may well have been from using them, but I don’t think that is the case. But the handle does protect you from it.
The ball ends are interesting, I thought it would be a lot more useful than it actually was. The reality is that it needs to be at quite an exact angle and you need to not change this while turning the key. I imagine this would be useful if you had to use them on something at an angle, but if you have the choice you will probably always use them straight on.
I have included an image of the set in its storage bag and you can see it is quite a nice size and can be stowed away nicely until it is needed, and the loop is useful if you want to hang it. In the video attached you can see me using the T handle on one of the keys and the first turn is done straight on and the second is at an angle using the ball mechanism, you can see how awkward it is using it at an angle, but to be fair that is a bit exaggerated as it is one-handed. The final image shows how the finish has started to strip off from the business end of one of the keys just from some light use
