“Push a button and the die will display a random number from 1 to 6 just like a dice! [The kits are] great for board games. [Plus], you get a free CR2032 battery with each kit!” applemount wrote in a description posted on eBay.
“[The kit] uses advanced on-board entropy collection to generate real random numbers. Soldering is required, [although] each part is clearly labeled on the printed circuit board for easy assembly.”
