Amazon reviews are very harsh on this mobile phone. The main objection seems to be that it isn’t mobile – it won’t fit in a jacket pocket or handbag, so it gets left at home. People also feel they are being treated as if they were disabled. In addition, there may be some functioning problems.
If you scroll down here, you can see it’s at least four times the size of a normal cell phone.
