Customer Reviews
Helpful service, slow shipping
I bought some YShield Shielding Paint and a Grounding Kit. The paint itself was good quality, and the staff were helpful when I called with questions about application. Shipping took about 8 business days to get to Perth, which felt a bit long. Everything arrived well-packaged though, so no damage.
Meter purchase experience
I purchased the Gigahertz Solutions ME3830B after doing some research. Ordering was straightforward on their website. It arrived in about 6 days, which was reasonable. The meter itself seems robust and pretty accurate for my needs. I found the instructions a bit dense at first, but managed to figure it out. Haven't needed customer support yet, which is a good sign I guess.
Good value overall
I rented a Safe and Sound Pro II RF Meter. The rental deal saved me a lot compared to buying it outright. It gave me a good understanding of my home's EMFs without a huge upfront cost. Definitely felt worth it.
