Buttons are beautiful visually; they really know what they're doing and I was honestly surprised how well they turned out. However, the physical finish on the buttons I received was ROUGH, and the buttons kept getting stuck down (caught on the inner lip?) or were slightly too tall for their enclosure (unpressable).
Litnxt's support team responded very quickly, I sent them a video showing the issue, and they shipped me replacements free of charge. The replacements were in equally rough shape, but I picked the better-looking of both sets and have a fully functional and very spiffy device!
