I noticed I'm missing two of the rubber pads under my Gladiator NX base. I have no idea if they got lost somehow or if they were missing from the start, this was not a problem when I was using it standalone but now that it is connected to a GNX SEM module, it's not stable. I have not seen a way to order replacement pads on the VKB Europe site. Is there a way to get some extra pads ?
