I'm back at VF. When I saw new version in Market I had to try it out and now I'm on my 5th generation.

This one is new for me and I can't seem to find mention of it anywhere else so far. Husband and wife both work in the office. Every now and them they will go to different items, like the air purifier or some other electrical unit and make a sound like they are clicking it's switch. Then they look at me and shake their head. A few times they have quit working after this but not always, and there is nothing showing up in the caption box beneath them to indicate what's going on. Seems like a power outage of some sort, the router is online and working. Any ideas?
