DualSim BlueSIM desktop phone

I Saw this advertised and knew I must have one. But the experience has been quite disapointing. Call quality is less than ordinary. I actually think my car kit does a better job in relation to quality. The user manual is also less than ordinary. I'd like a picture of the phone with an arrow telling me what each button does, but this is not provided. What IS provided are a few basic words - it's very much a teach yourself affair, and I am not a technophobe. The thing that REALLY gets me that if I bring my mobile too close to the phone it buzzes ! So really the mobile cant be on the desk when I make or take call. It also feels cheap - It doesnt feel like a quality instrument - probably because its not ! Would I buy another one? NO WAY !
