Thanko wants to help keep your environment silent with an update to their Silent Keyboard with an EX attached on the end instead of a shhhhh. They’ve cut 16.5 dB from the sound of the keyboard and to them that equals $52.79.
Seems a tad pricey for any keyboard, silent or not. But if quiet is your bag and all of that clickety-clack is getting on your nerves, why not give it a shot? It will take your money just as quietly as it operates.
