My unit has been great. The 1st year it was indestructible. Then this year I had issues when it got wet. Today I decided after a few days of rain riding and drying out at home and work, to adhere a strip of tape all along it's seam. Today, despite another MISERABLE morning commute in the rain, when I got to work it was still doing it's thing, good as new. It's in our server room drying out anyway cuz I spotted a water drop inside it. Maybe that came from my forehead when I opened, who knows - but you may want to try the tape along the seam if you're using it in the rain.
