So far so good. The only thing that doesn't work well is its infrared, which seems like it's not really "friendly" to "strangers".
Budget wise - it's not really that expensive and is strongly recommended for those who're looking for an almost-all-in-one type of phone... this is the ONE for you!
Functionality and Usability - Quite user friendly! Categories are well sorted and also it's not really confusing to understand the overall navigation.
Performance - I'm quite a regular SMS user while mildly receiving calls from friends and suppliers, and this phone just lasted me 3 - 4 days after being full-charged.
Misc - Ring tones are so-so for its volume while the games... the availability is quite limited! The camera, well... do not put your expectation too high, but is still "acceptable".
I have purchased an additional set of this kind and I am happy with its fairly good performance.
