Hi,
the buttons feels ok for me. I'm for moment with a beta panel but they gone change my panel because the firmware update is not to do with mine. This company did a good job on the panel and have no isseus with assigments to buttons. Realy good buy.
Buttons are backlite and verry well readable.
Picture of the backside of the panel and at night.
The buttons AA and AG are in the wrong line but verry easy to switch them. I don't have it done because this is beta panel.
