KRepublic’s 130 key switch tester that comes with a 2 in 1 Keycap puller + switch puller, a Red CNC aluminum 3 in 1 magnetic switch opener, as well as 150 O-Ring sound dampeners (diameter of 0.2in). This is the largest switch tester set I’ve seen on the market by a long shot. As you can see, this comes fully assembled with all of the blank keycaps applied. The bottom row of the 2nd base with the black keycaps are the unique switches that won’t fully sit into the base is how KRepublic designed it. I confirmed that with them personally. I’d keep them in a bag that I’ll include besides when testing as they could be easy to lose. The final images show what each switch is and where it’s located. This product will be packaged very carefully, but some of the switches may slightly jostle out of position when in transit. They can easily be placed back into the respective slot. Let me know if you have any questions!
