This arrived in three days on free delivery. The drive comes in a plain cardboard box, with the drive, a user guide for Windows 98 and a mini CD (not sure these will work in vertical CD drives as it may need a spindle to hold it in place).
Out of the box and plugged into a (new but basic) Windows 7 computer and the device was recognised and the driver installed automatically in under 4 seconds. It reads HD 1.44MB floppy disks recorded in 2001 and not used since with no problem and equally writes to them (the box says it will work with 720kB disks too). It needs to install the driver for every usb port but that is no hardship. The only glitch is that drive does not show up in the navigation pane of Windows 7 Explorer. It is there though, but it's necessary to click Computer and then double click the A drive when the icon for it comes up.
The drive works equally well on an 18 month old XP netbook. Detected as a Teac drive (so a recognisable pedigree), it was installed in a few seconds. By this stage, being curious, I dug out an old 1999 Windows 98 laptop. Following the user guide I loaded up the mini CD, plugged the floppy drive in the usb port, the computer detected it and then searched for and found the driver, installed it and guess what? Works perfectly, showing up as drive D: in Windows Explorer, so no conflict with the original A: drive floppy. Remarkable. I can't vouch for Vista.
The device has four glued on rubber feet and can be safely stacked on top of a usb hard drive for instance. It works at the speed of floppy disks, so not fast, but that's the disk technology not the device.
Does what it says and at a bargain price. Highly recommended.
