richms: Will give that one a shot if I need to record calls again. Ones I have tried in the past that worked sort of seemed to use the phones mic to record both sides so that the other end was really weak and couldnt be heard over the top of background noice etc.

I know what you mean but that one doesn't do it in that way. very unobtrusive and you don't even need to have it on loud speaker. The quality was actually really good too. Give it a go and call VM or something to test. Or wifes cell something easy.
