Review on 🔁 Efficient and Compact EZ DUPE USB Duplicator - 1 to 4 Standalone Flash Memory Drive Copier (Mini USB Plus) by Leonard Henry

I had to copy over 100 flash drives (fd) with 3.2GB of information to new 16GB preformatted flash drives. Round one: Followed the instructions. All 4 fd uploaded to duplicate. After a while, 2 fd flashed red, which indicates a malfunction of the fd. 2 more exchanged and measured. Duplication time was 12 minutes with all 4 turning green at the same time. The duplication time was 12 minutes, which is 300% slower than the advertised time. Try again. round two. 4 more loaded 3 of 4 flashed red. Draw 3 and leave the calculated one. 40+ minutes later it still works. There is no more time for that. He pulled out the last fd and stopped. Third round, the next day. Loaded 4 fd, one flashed red after about 20 minutes time. Left it to see if the pull might spread to others, causing them to blush. like it happened for the first time. Never blushed. However, over 1.5 hours later, it's still copying to 3, which never turned red. At least the duplication time isn't nearly as high as advertised. (2 GB/min) Performance was otherwise unstable and unreliable. The formatting was fine when pasted, but got corrupted soon after. I believe this device has been corrupted by formatting. I also don't think 50% of my new FDS were bad. Note: After unplugging the fd after the red blink, all fds that are unplugged need to be FULLY reformatted - no quick format. Each takes about 20 minutes. Summary why take the risk. Go ahead and buy something else. I wish I had. I will return it and buy another brand.
