When I'm not using my eGo/clearo I generally try to set it upright. On the end table I have a nice little oriental vase, but at the computer I use a coffee mug that also contains a few pens and a letter opener. Well, yesterday my wife left her half-full coffee by the computer....you see where I'm going, right? Without even looking I dropped my Joye passthrough into the coffee and didn't notice until I reached for it again about 20 minutes later. I was sure I'd ruined it - dried it out and it didn't work. But after letting it sit for a couple hours, it works fine, even the USB. Just thought I'd post a li'l testimonial for a well-made product!
