ROFL, another magnet coming loose. John, you're not the only one to whom this happend. And not just with the CXS, but with centrotec bitholders in general. Happened to a bitholder of mine. Many people have reported a manget coming loose by now. The glue Festool uses is crap. I can't believe Festool stil uses it after the gazillion times this complaint has been made here on the forum.
That sad, the CXS certainly is NOT crap. I don't have one, but we read many testimonies here of satisifed owners. Too bad your battery went dead, but you're the first person to mention this so I don't think the CXS is to blame, just a bad battery, which can happen on occasion. I do hope you contacted Festool and got the faulty battery replaced, and the magnet fixed. Better would be to fix the magnet yourself with a bit of superglue, works a lot better than Festool's glue. Once you get these little kinks sorted out, I'm sure you'll grow to appreciate the CXS.
