Thank you for sharing your experience with your Phi 02. We are glad to hear you're sleeping better since you've been using it! There's really no need to move the device daily (or ever), since the protective field is very large and will protect the entirety of your house and beyond. Also, the field is the same strength throughout its entire range, which means it's just as strong if you're right next to us as if you're a few rooms away. The best way to take care of your device to ensure it lasts for many years to come is to keep it in one place 24/7, in an area where it's protected from being bumped or knocked over, or exposed to water or excessive humidity.

The occasionally flickering of the light is normal, and is actually how it's supposed to function. The light should be solidly lit most of the time, but every half minute or so you will notice that it flickers for a couple of seconds. This is evidence of the dual band nature of the device; the flickering is when the standard Blushield algorithm is being emitted into the environment, and the solid light is the additional algorithm we added to the new models to give better protection against 5G. This continuous signal is interrupted by the standard Blushield signal for a couple of seconds, repeating every half minute, to create more variety/change in frequencies, which living biology responds well to.

The light should stay at the same brightness, but at times it may look brighter or dimmer in contrast to lighting changes in the room, which is normal. Please reach out anytime if you have any other questions about your device!
