Query: DON'T BUY THIS MODEL

I got two of these watches in six weeks. The first one died two weeks after getting it. The screen went blank for no apparent reason. I thought it was a fluke and received another one. That one went blank four days after getting it, again for no apparent reason. When it did work I loved it because of it's great functions. However, it seems Casio may have a production problem due similar complaints about this model watch. Very disappointed.
