Peace of mind
This is our 4th purchase of a Blushield.
We love it. I’ve notice the difference in the behaviour of our cats. Much calmer.
We recommend Blushield to everyone.

Great for Travel!
We really enjoy having this device for travel on a regular basis. We have the bigger models of the blueshield products in our home and our workplace, so when we travel outside of those areas, we can definitely feel the effects of the EMFs we're not used to feeling in protected areas. We really enjoy having this for that temporary help until we get back to our place or can get to a place where we can plug in our other larger unit (like a hotel we are staying at).
