What is the opinion of Reddit about the
Smart Duck xs87 87 Key Mechanical Keyboard kit 80% TKL hot swappable Switch Lighting Effect RGB Switch led Type c Software Macro (SmartDuck XS87 Kit x1)?

Can’t speak for how decent these are but I found these the other day when I did some research for myself.
