Query: Incredibly disatisfied after only 1 1/2 years

As many others have reported, mine too has lost the ability to record. Its been used for maybe 50 hours of recording in the past 1 1/2 years and is now completely worthless. Don't buy it! It'll work great for a bit, then fail on you when you most want it to work :(
