This is more like it! Readers should read my other review on a different £9.99 model which I sent back because it was temperamental with Windows 7. This worked first time beautifully across a range of machines all running Windows 7. It reads the discs, writes to them and asks you to format them only when they are actually uinformatted. It comes with no installation disc because it is truly plug and play and doesn't need one. On all machines, Windows recognised the device and found the correct driver.
OK, it is about 3 quid more expensive (peanuts) but now I can actually get on with what I wanted to do in the first place, rather than battling with some rubbish that refused to work properly.
My only criticism is that the USB lead is rather short, less than 0.5 m. You can't stand it on a desktop machine and plug it in round the back for example. You've got to use the front USB's. This is why I have marked it down by 1*. But it is said by another reviewer to work with a USB extension lead. I haven't tried it yet, but I expect it will.
It is actually a TEAC drive inside, which probably says it all. If you want an external floppy drive, grab this one.
