Haven't tried one of these myself yet, but it looks like an interesting product in our world of ever-increasing EMFs that we live with. Hoping some fellow ozbargainers find one useful!
Blushield has been developed in New Zealand over the last 30 years.
There is plenty of information, scientific studies and more available to read on the product website.

There are quite a few user reviews on the deal page, and even more on the individual product pages.
And a high level summary from the product page:
Blushield is an active EMF protection technology designed to protect users from the health effects of man-made electromagnetic fields from mobile phones, smart meters, Wi-Fi, 3G, 4G, 5G and all other sources of EMF.
The Blushield Plug-In is recommended for homes and small offices where exposure to EMF is low to moderate. It uses very little power, yet covers 45m in all directions. It is best plugged into a central location within your home, not the bedroom. A hallway or lounge area is recommended.
The Blushield Premium Portable is great protection for when you are out & about, covering 3m in all directions and can be carried on your person, pocket or handbag.
Read full product page information for all the benefits.
UPDATE: It is so easy to jump to conclusions and assume what the product does! These don't block EMFs.
Simply click through the link and you'll see more of what they do:
Does Blushield block EMF?
No, Blushield does not block, shield, remove or modify EMF. WiFi signals, mobile phone signals and other smart technology is not affected the presence of Blushield.
Blushield works by sympathetic resonance, allowing your body to tune into its natural scalar frequencies which it recognises over the man-made frequencies from smart technology thus protecting you at a cellular level even when EMFs are in your environment.
They also have a 30 day money back guarantee if you want to try out the product to see if it works for you.
Great for when the odd solar flare wipes out all digital devices on earth but you still want to play candy crush
