After turning it a bit, I felt like it could fall apart at any point.
Indeed, it ended up popping while I was attaching it to my keys. And even more, some corners got separated into 3 individual pieces and I had to re-assemble them.
Then, after the first day bringing it outside, when I returned home I found that a centre piece fell out somewhere. I have not yet been able to find it.

All in all, extremely feeble, not really fit for having it in your pocket.

The twist is smooth, has a nice design, the plastic is quality and smooth to the touch, I am satisfied with the design, the quality of the plastic and the twist, I recommend it
