<p class="MsoNormal"><span style="font-size:11.0pt">The older XW’s were solid. We have a lot in the field. Keep ‘em dry and don’t overheat. Can’t think of any that just failed on their own, couple from customer stupidity. Had a few units that had some heavy
use that were starting to throw over temp codes periodically so proactively replaced. As Pieter said, the XW pro series is junk and have had to swap out almost all of those. I run my home and shop off a 2010 XW6048.
