Query: Great concept but needs work

I love the idea behind this device, and I loved it when it worked. But like with some of the other people commenting here on this product, it didn't work completely when I got it - some of the functions simply didn't function - and the outdoor temperature function stopped working completely after a few months. I had no luck with customer service. If they work on reliability and extend the length of their warrantee, this will be a great gift item.
