The adapter works great. Tested on the Switch and the Galaxy Note 10+ and everything worked great until I tried removing the flash drive from the USB port. This is the best shot of any USB port I've seen. The connector held onto my flash drive so well that the USB end of my drive was still in the adapter when I pulled it out. Luckily I was able to fix the flash drive and didn't lose any files other than the sacred cow. The connector needs to be adjusted to loosen it up a bit, which is a major downside to this otherwise great adapter. I used a pair or needle nose tweezers to pry 2 prongs off the inner plastic piece and this loosened it enough that it wouldn't hold with the Hulk's power. I couldn't give more than 2 stars because it almost destroyed a very good drive (Samsung 256GB).
