Has anyone received a slim that has a short in it? I got mine when Massdrop was having the sale on several ready to order items so I bought it, and a month or so ago it started to not show up on my computer if i moved it the slightest, and id have to re plug stuff and hope that they get that 'sweet spot' where it actually connects. I tried different cables, usb ports, and it all seems to point at the device itself. I'd rather not just have something sitting on my desk that i can't use consistently
