Query: Didn't last 2 months

I wish I would have read some of the negative reviews before buying this simply on the positive ones. This poorly built little device worked fine for almost 2 months before it just died. The display just went blank. Of course, my first thought was that the batteries were dead. After replacing them with new batteries, the display showed a bunch of partial digits, then faded away. If I paid 5 dollars, I probably wouldn't care as much. Before buying this, READ THE NEGATIVE REVIEWS, not just the positive ones.
