I am a user of SGH 210 (shhhh I bought it from the grey coloured market). But the instrument is amazing. It is smaller in size with feature packed to the brim, very user friendly and of course, with a technological edge. In this age when the technolgy is getting older within hours, I feel I can very well work with this instrument for quite a while. The blue coloured screen is soothing to the eyes, and provides differentiation from the other products in the market. The solid name SAMSUNG too is a household name in electronic gadgetes field. For me it is very convenient to carry as well, coz it can easily fit into the shirt pocket, without unnecessary bulging. But slight disadvantage in this set is, its ring tone volume is little less (as compared to the other instrument I was using earlier), this sometimes results in ’call missing’ in some shor-sharaba
