Title: Lost sync with dongle frequently, stopped working completely after 18 months
Review: I like this keyboard... when it works. I'm not a heavy user, and yet it would stop working every couple of months or so. By trial and error I figured out that to revive it, I needed to remove the batteries, wait a few seconds and put them back in, then re-sync. Then finally it seems to have completely failed just now, after about 18 months. I can't revive it anymore. I find it unacceptable for modern electronics to fail so quickly.
