Samsung M110 most of the protection is afforded by the thick rubber casing which effectively seals the M110 against the elements and provides shock adsorbing properties. Clad in either a black or olive green housing, the M110 / Solid looks a little more toned down than it's JCB-branded competition. It's also a smaller and significantly lighter handset than the TOUGHPHONE too, at just 95 grams compared to 130 grams for its rival.
