Pros and Trade-offs

For most users, the Ajazz AK820 Pro is the more versatile choice, offering a unique screen, more portable design, and greater feature set like RGB and a knob at a similar price point. Only choose the AULA F87 if your absolute priority is a potentially quieter typing experience from its described sound-dampening layers and you do not need RGB lighting or extra features.
