Found this yesterday on the DX site, thought it was quite amusing so worth it for the fun factor.
Not really a handsfree set as you still need to use your hands.
Hate crowded trains and public transport? Start using this and people will no doubt give you plenty of space, thinking you are wacko!
Looks a fun item though, and would make a funny gift for someone.
Just ordered mine and it concerted to £3.75
Its probably better to hold and more comfortable than holding a mobile for a long call.
