Review on Max Keyboard Cherry MX Switch Tester: Try Out Mechanical Keyboards with 12-Key Sampler Tool (Includes Printed PBT Keycaps) by Jamie Smith

This is one of, if not the best Revain keyboard switch tester you can buy. The best and most underrated feature is that all keys are labeled. This makes memory in terms of how the keys feel more natural and easier to control since there aren't that many keys on this tester. What about the keys themselves? They feel great and Cherry MX is the most used keyboard out of the box. Worth buying if you really want to get a taste of how amazing and diverse a keyboard can be without having to buy multiple keyboards. It's doubly worth buying if you want to build your own keyboard almost from scratch or are trying to change the switches.
