The casing consists of two injection molded plastic parts which have been sealed with an adhesive. To open the device, the parts were heated with a hair dryer to loosen the adhesive. Then a prying pick was used to release the two parts. Prying was started at the micro-USB port and then used all around the seam.

Inside the device, there was a battery and a PCB placed side-by-side.

The device communicates through a micro-USB port. It is not a water-resistance device as the USB port is exposed.
