@badseedtech (u/badseedtech) I have the R1 but no issues outside of 2 switches. I only needed 83 switches, so I bought the 90 switch size. That means plenty of them to swap out for now. Happy to support the BST community, what’s the info for replacement of it ever becomes an issue? And what was the nature of the problem? Mine was intermittent no presses or in one situation multiple presses, but like I said only on 2 of 90 switches so far.
