Actually, I can be quite short about this stick. In my view, 2 criteria are important, the storage capacity and the speed.
I initially bought this stick because of the storage, speed was an afterthought (with the 10MBps that Coolblue specifies as max write, I didn't have too high expectations anyway). I've done several tests, and the same trend always emerged; the stick starts the first few seconds with a decent speed of 100 MBps (theoretically USB 3.0 is 625MBps, everyone knows that you can be very happy if you get 1/6th of that). Ideal if you want to copy smaller files. However, if you want to copy a few movies (take 6, combined a 13 GB), the speed drops to 12 - 17 MBps, values that are among the lowest on the market. Well, still better than the specs stated by Coolblue (ie 10 MBps).
Maybe someone wonders why I'm writing this now despite I knew that the max write is supposedly only around 10 MBps, just a matter of giving realistic speeds for info. That's what the reviews are for, of course!
Conclusion, ideal stick in terms of price / storage, if you want a faster stick, it is best to start looking for at least from the €40 category.
