OCC posted a review on the NK Blueberry Switch
A quote from the article:
After spending what I believe was about two months using the Gazzew Boba U4 Silent Tactile switches, the time finally came to swap to a different switch. As the title indicates, this different switch would be the NK_ Blueberry from NovelKeys, which are also tactile switches, technically. I feel that qualification is necessary because the instant I started using them, the differences between the tactility were very apparent. Of course there is more to these switches than just the tactile bump, which I will be getting to after wrapping up this introduction.NK Blueberry Switch Review
