    I bought 2 of these for my kids' Toshiba Fire TVs. They seem to work just fine. Here is the only issue I have: I leave the flash drives in the TVs at all times. Sometimes when I turn on the TVs, the TV will give me a notification that the flash drive was improperly removed. My guess is that this is an issue with the TVs, NOT the flash drives. Since I have no way of knowing for sure--unless I try a different kind of flash drive--I will rate this 4 out of 5 stars. Would I recommend it to someone? Absolutely! I have no regrets. (If I did, I would just return them.)

    This is a great flash drive at a great price. 128gb is huge. Only reason I did not 5 star it is due to its light weight and cheap feel. Other than that no complaint, it even has security software.
