We Make The Invisible, Visible. As an Electronics Engineering Technologist, Rob Metzinger – SLT’s President and Founder – became extremely concerned about the interference of man-made electromagnetic fields (EMF) on the human body. Rob’s interest in EMF began in the year 2000, and Safe Living Technologies (SLT) was founded in 2006 – a time when wireless technology was beginning to boom, and without any caution or restraint. Rob furthered his education to become certified as a Building Biology Environmental Consultant (BBEC) and an Electromagnetic Radiation Specialist (EMRS) through the Building Biology Institute. He has been an educator and course developer in the advanced studies of EMF/EMR since 2008. He strives to be a leader in the field of education and advocacy around this complex issue. An alarming number of recent studies indicate that electrosmog has negative biological impacts. See our studies page and the Bio-Initiative Report for further details. It is in our best interest to minimize exposure to these invisible forces as much as possible.

I had a free 15 min. consult with Safe Living Tech and found it to be very helpful. I had written down several issues that I needed advice on, and got good, clear, answers.

Over the years that I dealt with S.L.T., I consistently received excellent service.
The only problem I sometimes encounter is that I live on the West Coast, in quite a different time zone.
Keep up the great service!

Unfortunately I did not have a good buying experience. The meter that I purchased had been tampered with, or used and arrived with a broken package seal which was resealed with another seal. Extremely disappointed since the process to ship and return a used product cost me $37.71.
Update: Tony at SLT extended a bribe: “I would like to refund the shipping fee. If you are willing to update your review on Trust Pilot as resolved and update your review to a 4 star or better.”
Me: I don’t need the money back. I think it’s important that purchasers understand they are purchasing from a ‘reseller’ and that the product will not be shipped as ‘new’. Thank you for your attempt to raise the star rating.

Better help than I expected on a shipment. Zachary handles the hell out of things and solves the small problems before they become big or time consuming.
5 stars on service. I feel like family. Really.
