So far I am liking it what I see for the price. My MAIN concern would be the batteries. I find they don't last very long, or at least in the camera I had the batteries didn't. We always had to buy lithiums so that it would last 12 hours, and those were about 12$'s for a pack of 4.
Other then that all I see is its not the best in lowlight which just means your photos will be a bit grainy because you will have to Up your ISO, and once your ISO hits 400 with this camera it starts to get grainy or muddy.
Don't let the low light issue deter you though, as it does have a flash, I haven't found how far the flash is effective though. And people who have made reviews from using it that arn't professionals are finding that as long as you are in good light it seems to compare up pretty good in terms of clarity and quality.
Overall I think its a nice little find. As long as you are ok with the batteries.
