Has holes enters the moisture, otherwise ok buy recommendation

Operation and data transfer is OK. 8GB hand me completely.
However, the device HOLES! in case in which even the smallest amounts of sweat can scrap the unit. Why did you just called sports? Amazon has converted the unit easily and the new device have I taped to the side and sewed me a little Unhängetasche so that the device does not have any contact with the skin. The clip is thus rather little applicable for me. The headphones are of course useless, since massive cable noise. (Recommendation: Sennheiser Headband). Battery life reached for me, when I boot the machine after 2x listening to music or about 3-5 hrs. (It's about half full defrosted display). Some versions do not have a key lock, with the new firmware there then. Practical: loud and quiet are not disabled (sometimes impractical: off is not locked).
