No issues here either, and I've done a lot of miles in the rain...hard rain too.
I did have any issue with the left saddlebag on my 08 C14 though...about a foot of the rubber seal came loose and was being a pain...I had to kind of prop it into place when closing the case. I finally glued it back in, and it was fine. In any case, loose seal or not, the cases never leaked, before or after....and I've ridden in the rain for days on end.
PS: I still haven't forgotten the old days...lol. Getting up in the morning while on a bike trip, and putting all your wet gear back on....what an awful feeling...lol. Then, packing all your stuff into garbage bags and grocery bags...before putting it in the motorcycle "luggage" you tied to the bike, and hope and pray that the rain wouldn't work it's way into the bags somehow before the next stop for the night...lol.
Unless you've done things the hard way, you can never truly appreciate things the good way;).
