I bought this so-called "refurbished" unit from Tech Venture. It had a number of major issues. The battery would drop 80% of capacity reading withing ten minutes. The camera froze up any time I tried to use the function where I press the shutter button while off. The audio was unusable with loud hisses and pops over every video. Do not buy a refurbished unit from these guys as there are obviously no refurbishing or quality checks going on.
