I have a general recommendation for the M1 model and not sure if this is the best place for it?
The display screen and pulse lights operate in the blue & green spectrums. Research shows that these are bad for sleep (melatonin production) and can potentially lead to macular degeneration over time.
Is it possible to start producing the PEMF devices with a red or otherwise warm colored display and lights? This would be much more comfortable and convenient to use especially at night and I don’t think it would affect basic function.
I currently have to wear blue blocking glasses and cover up the displays with electric tape at night in order to avoid the blue light which is inconvenient.
Love the product!
