I bought both 128GB 3.0 and 32GB 2.0. Both initially had problems with malfunctions. I have a 128GB 3.0 drive for essential work related stuff and a 32GB 2.0 drive to see if they are truly waterproof. I put a film on 32GB 2.0 and dropped it in a glass of water. I let it fully submerge to the bottom for a full minute. Then I swung it around and twirled it for another minute while it was underwater. I've also opened and closed the latch several times under water. After a thorough soak, I dried it and let it sit for two hours. After that I connected it to my desktop and was able to read and play the movie stored on it. It worked for me, but I am in no way responsible for damaging someone else's flash drive. I only did this as a test, but no smart person should ever intentionally put their USB stick in water for any other reason. There were some issues connecting it to my desktop the first time, but I haven't had any issues since. Most of these waterproof/keychain sticks are fake/scams and I did a lot of research before deciding on this one and I'm happy with it. However, if you are serious about storing your data and keeping it safe, just use an internal or, failing that, an external SSD. But it's a good and reliable way to store your data on your keys.
