I must be the exception because I haven't had any issues with my 5'er since I moved in a little over a year ago (has it been that long already?). I did have a couple of the recessed light fixture lens fall out on my second trip, but I think they just weren't installed all the way initially, because I have made several more trips since then and no more problems.
All of my main systems were and are working perfectly.
Keeping my fingers crossed after a year of full timing.
