I succesfully sued Carphone Warehouse over a faulty telephone they refused to replace.

You save £5.00 (£25.00 instead of £30.00) but otherwise I thought it was easy to do and user friendly as they say.

The problem is that if you win you need to enforce it and it may be spending good money chasing bad.
