Summary: I didn't use it more than a few times. It's never been out of a drawer for more than a few hours. Now it won't mount. It's useless now. I hate USB flash drives. I've never had one to last more than a few months.
Summary: Extracted from description Compatbility: >> Operating System Compatibility - Mac OS 9, OS X, Windows 98SE, 2000, Me, XP, Vista << Specifically ordered this over preferred Kingston for Win 98 as stated above. Shall see !
Summary: I bought this last year. It lasted a week or two, I don't remember. It's unrecoverable and no computer recognized it, and I've never found any driver software for it. It's about to go into the trash. I bought a different Lexar yesterday, not remembering I had this piece of junk. I'll found out if it's a piece of garbage too, I hope not.
Summary: I have used Lexar exclusively for years for flash media from jump drives to microSD memory in the cell phone, so I have been very partial to Lexar until now. Several months ago I purchased two 4gb FireFly usb jump drives. Occasionally I have encountered that large files (200 gb) will not open once copied to the USB drives. I contacted Lexar tech support three times regarding this problem.
Summary: Hello. 1 star is too much for this product. This product, the Lexar LEJDF4GB JumpDrive FireFly - 4GB Capacity, worked for about 3 weeks before it failed completely with about $3,000 worth of data loaded on it. I had just enough time to load it with data before offloading. I paid $27.50 for this product and as you read on you'll see it cost me alot more. Of course, I contacted the LEXAR company about their product many times to get assistance with the problem.
Summary: I bought this for my critical financial files and some other absolutely necessary data. It lasted about six months if that. I formatted it and tried to get it back in shape. Nothing worked. I'm going to go back to Kingston DataTraveler Elite 4gb. I have a Kingston that has outlived every other flash drive I've had and it's still going strong. Just not enough storage. They cost more. But you get more.
Summary: I really can't begin to describe how slow the transfer rate of the Lexar firefly is. The transfer rate makes it nearly unusable for anything but a few small files. It can take literally HOURS to transfer 500 MB if it is a bunch of small files you are transferring. It is a little bit faster with fewer larger files. However, I recommend looking for something else. I am very disappointed with my purchase.
Summary: I bought this item, attracted by its small size. However, I soon discovered that this item is not speed rated and transfers files at turtle rate. It took 3 minutes just to transfer a 50 mb file. The same file transferred to another drive took just seconds. If you'd like to transfer anything big, which is why I am getting a 2 gb drive, it might well be taking hours. There are other lexar drives with a lot faster speed..
