I'm lucky. DH checks. I've almost washed my phone once - it fell out as I was putting my jeans into the machine and I hadn't and wasn't going to check.

However, I have washed the USB stick I used to use for work on a couple of occasions... Tumble dried it once, too. It still works, not that I have any idea of where it is now - but I checked it on work computers first so I wouldn't blow mine up!
