Summary: I plugged this into my PC running Windows 7 and it was immediately good to go. It's formatted to FAT32 and I reformatted it to NTFS after using the click-thru Activate Warranty link pre-loaded onto it. Click the link and you also have access to a backup software suite too should you need it.
Cons: Returned one after much wrangling with maker. It claims to be 64GB, but was actually 62GB. After 2 months of back and forth emails, they finally send a replacement and it's not 64Gb either... it's 63GB. This is wrong, but they claim it's in their "specs" to be within their range of error of actually being a full 64GB... what is that????
Summary: I used these 16 GB models to run Linux (one with Mint; one with Ubuntu). I used the 32 GB model to write a story I am writing. Two more are coming; fast read/write speeds and no complaints! For this price, quality, looks (they look exactly like the picture), and USB 3, they are a steal. If your in the market for a USB 3.0 thumb drive, look no further.
Summary: It's only 29.9GB, 2.1GB less than described is a lot for me. It sometimes just ejects itself from my Laptop when transferring files or its just sitting there and then I'd have to plug it back in. I have over 5+ different flash drives and none gives me problems like this. I'm a bit dissapointed.. because I also have a 3.0 16GB flash drive from the same brand and it works fast and great. I guess I received a bad flash drive or something..
