I found they worked merely okay. Maybe I just didn't have them positioned correctly but it was a little tippy. This was on a lily58, so the size may have made good balancing a bit tougher.
Either way, I switched them out for the magfrotto tenting, which works super duper well
Oh okay nice! I'm glad to hear it! I had the decently balanced but thumb keys would tip it a bit. So I just decided to upgrade so I wouldn't have to deal with it.
Plus the new setup is modular so when I assemble my next keyboard all I need to do is add magsafe stickers
