Hey, We've just bought a batch of Saturn 4 button wireless switches, having a couple of issues. Out of 3 switches, two of them are firmware 1.1 and one is 1.8 although they were all ordered in a batch and sourced from the same supplier. The 1.8 version is fine and working as expected. On both of the 1.1 firmware switches the build quality doesn't seem anything like as good with the buttons slightly sticky and the fit of the cover feeling slightly out of alignment which i think adds to the buttons sticking. One of them is also noticeably flickery on the primary channel, which is not seen on the 1.8 unit. My question would be - can anyone confirm if there have been physical changes on these units since earlier versions? Will the 1.1 firmware potentially be more prone to flicker than later versions? And what's the latest firmware version on the Saturn wireless switches that should be supplied if these are coming as brand new stock? Thanks Al
