The new DS (double sided) version of the 3×3 feature the off-center nibs on both the pusher and machine body, making it possible to attach keycaps to all of the switches (rather than just half like the previous versions), it is more efficient to break-in off center.

Speed can be adjusted (with speed controller accessory) for this one with the speed controller add-on, but don't let it get too hot. Because of the summer heat, it is recommended to put this in a well ventilated place, ideally with a fan pointed at it as well. 

If the motors break within 1 month of you receiving the unit, I could provide replacements, but I won't be able to help after that time period (I have no way of knowing how long you've been running it for

Other Info:

• Off center mode – applies more force to the side of the switch by pressing on the side of the keycap (one side at a time, the user rotates the switch plate to break in the other sides).

• The machine is quite loud, you’d definitely want to place it in another room when running it. I suggest placing a cardboard box over it to slightly block out the sound. Unfortunately I do not have any ways to demonstrate the noise level.

• Carbon brush motor – more durable than copper.

• Injection molded gear box w/ nylon gears (not made by me obviously).

• 240+-10%APM with all switches installed – speed changes based on amount of switches & spring weight. There might be variations in speed, it is suggested that the user measure the speed themselves based on what switches are used.

• Fully assembled and ready to use out of the box.
