Really bought this for the ability to record audio during note taking. Tried it during an important meeting yesterday and it was a total fail. Audio was muffled and kind of warped. Like it was coming from inside a barrel with an echo. Anyone had this experience. Definitely a deal breaker if I can't get this fixed. Still disappointed with the charging as well. The only charger I can be assured of charging it is the $40 one from Microsoft. They have false advertising in their claims that this thing charges with any micro USB charger.
