I have had my Grandee now for four years, and I am on my second remote. The first one was replaced under warranty after it crapped out in 2 years. I am not looking forward to replacing another one out of pocket when it inevitably dies, but I'm sure it will be cheaper than retrofitting. When it works, it works fine for me. Once in awhile it reboots, but not a big deal. So far remote number two is, for the most part, bug free.
