Review on Muhoop 2TB Waterproof USB Flash Drive - High Speed Memory Stick with Keychain for Data Storage, Transfer, and Backup - Durable Thumb Drive with USB 3.0 (2000GB) by Jon Smith

The machine arrived on time. Looks good and I was surprised. I bought this device as a backup during a trip. I started copying several files, about 200 gigabytes. I run most of them to make sure the video is ok. When I got to my destiny I opened the folders and even when you could see the files there more than 50% of the files were gone. The same files I was running when I did the copy! I tried to recover some of them with a data recovery tool and it turned out that most of them were in bad condition. Recovery proved impossible. I do not recommend this device. The price is great for this amount of storage, but it doesn't work. Please try to buy another brand.
