It seems well built overall but there are some issues. 1) there is no Caps Lock light. Ironic that a keyboard with all that back-lighting doesn’t have an indicator that Caps Lock is on. 2) there is a function button to the right of the right hand control button. After years of “command /“ by feel to create a new playlist in Pro Tools this has really slowed down my workflow. Couldn’t they have put the function key somewhere else, like above the numeric keypad? 3) one of the modifier keys seems to get stuck sometimes, which causes some strange problems. It’s hard to tell which one it is but it’s intermittent and a huge inconvenience when it happens.
