One of my Darbees always reset itself since new and the one remote never worked ALL THE TIME. However, they have gotten worse. Both problems have become much more frequent to the point of unacceptable. Looks like I will have to re-email Darbee as they have not replied. Both Darbees are less than a year old, just barely.
Fwiw, the very first Darbee I ever ordered was a Cobalt one that acted up right out of the box and was returned. It's remote never even worked. I love the tech behind these things in what they do for the image, but quality is highly suspect. In my particular case, this is a 66% failure rate. Wow!
