My Varia lights were purchased last Friday (March 18). So far, I have found it very difficult to make the "Device Key" on any of the three units work. I press hard with my thumb, and usually, nothing happens. I try again, and maybe again. I have even started using the edge of my iPhone case to press on the key - that often works for me.
Does anyone else find the key hard to press (and have the light recognize that you pressed it)? Does this get easier after the lights have been used for awhile?
