I bought a bunch of them while they were still in production; I have gifted a few to family and friends over the years, and still have one NIB for when the two I have and use break/get lost/stolen. Great camera- buy it if it works.
Maybe I'm the oddball but I like my Mju I (Stylus Infinity) more than the Mju II (Epic). It seems quieter and more substantially built. My Mju II also exhibits more lens distortion.
Both are great fun, easy to use and slip into any pocket.
