"Time for another keyboard switch review, but this one is a bit different from the last two for the Silk Yellows and NK Creams from NovelKeys. For one thing, these are the Gazzew Boba U4 Silent Tactile switches from 1Up Keyboards, and for another I have been using them in the 1Up Keyboards 1UP 60 HSE 2-Plate Keyboard Kit I put together a while ago. Both the kit and the switches were provided by 1Up Keyboards. The previous two switches I worked with were in the NK65 – Entry Edition build, and because of differences between the case and plate, the typing sounds cannot be directly compared. Another difference, which is obvious from the name of the switch, is that these Boba U4s are tactile switches, while the other two are linear."
