I recently purchased this online as it said it was a genuine Blackberry mains charger, so I thought it would be reliable. However, when it arrived I discovered that it was missing one crucial attachment- the actual British plug! However, I needed it urgently so I put the European attachment on and used a travel adapter to make it work.
Obviously it is my fault for not sending it back and getting a refund so I'm not here primarily to complain but only to warn anyone purchasing this to check that it has all the attachments it says it does before using it!
