In my local 99p store (Liverpool city centre) they had these in stock, now I know they're not huge storage wise but for 99p you can't complain.
installation software - CD.
Specs on the box reads:
Supports USB 1.1 & 2.0
LED indicator, connected, in use, reading, writing
No external power supply needed
Hot plug and play
Access rate: read 8mb/s max, write 7mb/s max.
I think it's a good buy for 99p, happy money saving etc. Sorry can't find a picture at the mo, will try later.
