I have ben using this for a couple of weeks and it performs very well. Very good signal strength even in difficult areas. Very good display, the menus are logical and easy to use. The size of the screen limits internet use, GPS etc. but they all work. This is really built for talking and texting, everything else is a bonus. The keypad is particually good, even with gloves. It has large keys and a good 'rubber' type feel that makes it a pleasure to use.
It does not feel as solid as the B2100 which I had previously. That said it appears to be very rugged and should with stand a hard working life. The torch and cord loop are useful.
Overall nothing negative to say about this phone. If you primarily want to talk and text and have an easy to use phone with a good keyboard that can withstand the odd bit of harsh treatment then here is your phone. The battery has lasted a couple of weeks switched on 24/7 with light voice use and loads of texting. A worthwhile addition to the Samsung range.
