The Joybook A53’s testing requirements reach beyond the industry standard of 30kg pressure testing. Instead, it’s made to surpass 50kg. What’s more, the Joybook A53 is subjected to 25 additional tests — including scratch resistance, hinge, compatibility, high and low temperature, drop, and vibration tests. Even the keyboard is subjected to more than 20 tests designed to ensure that it can withstand 8 million keystrokes.
