Query: Great... when it was working.

I bought this, at a very reasonable price. It worked for a week and then, when the first set of batteries died off, it never worked again. It won't even power on. But, for the one week it DID work, it was decent enough for the price I paid for it. Not sure if I'd recommend it, mainly due to the fact that it no longer works.
