Oh, what you pay for, you get! That's the law. Compared to previous flash drives from well-known companies, it's day and night. My critique is solely about the reason it was purchased, i.e. for music playback in the car from a source (Alpine UTE-200BT).
I'll start with the design/appearance: Simply beautiful. Yes, it's small and runs the risk of getting lost, but it doesn't run the risk of accidentally damaging anything in the car like other bulky flash drives, possibly even the source's door.
Its responsiveness and speed surprised me, and I'm always speaking comparatively to previous flash drives and how they behaved with the same source. I didn't even have time to plug it in and it immediately read it. I exclusively used FLAC files in 24/48 (the maximum allowed by the source).
It played 150mb files as soon as I pressed play, it didn't struggle with playback, not even during fast forward. I didn't notice any temperatures, to be honest, as the trips were short.
However, my initial impression is that it's a reliable/modern flash drive. No matter how long it lasts, I consider it worth every last euro. And yes, I would buy it again. Must buy!
