For 10 pounds its pretty damn worth it! It does the calls and the texts and thats it! Plus it has a qwerty keyboard which makes it simple to enter the text in!
Pros: good battery life, good keyboard, nice voice clarity,
Cons: small screen, No WIFI, no BLUETOOTH.. oh I'm joking, of course you are not going to get that with 10 pounds, lol.
Brilliant phone, well worth it! Especially if you don't want to damage your new shiny iPhone at work! :D
