I have never delved into the menu on the Dani Box, i.e. you may have had some button selection turned off, but I think there is more in SBS that can be done.It moves, but not the same way as the up button. I don't have the heart at the moment to test it some more so that I can describe this better.
I bought it in January 2019, so no warranty.
It has been well treated all its life. No leaking attys, no violence.
If, on the other hand, you have to dismantle the mod a bit, I can console you with the fact that the Dani Box is extremely well designed, 3 Allen screws at the bottom, the bottom plate off, there are two long locking pins that you pull out with wick tools, or a needle.
Then you push a little on the bottom of the board and the top plate starts to lift, and you just pull up the top plate and everything comes out easily.
Dicodes has built the mod module-wise.
I changed parts in mine such that they became stabwood, the first one was of course the worst, the other two were maybe a 10 minute job.
