Perhaps the quietest keyboard I've owned. It might sound loud in the video, but it's much quieter than regular chiclets.
It has brown imitation mechanical-membrane switches which feel somewhat tactile. The keyboard has anti-ghosting on the main section. The keys are quite stable as well.
$10 on Amazon.
