Every word of the ad was true! I ordered, received, put on. After about 30 min, my mind reported ...clear.

I’m really glad I decided to invest in the Havn beanie! My friend and I even put it to the test by placing his phone inside the beanie, and his earbuds lost their signal. That was pretty impressive to see firsthand! Since wearing it day and night, I’ve felt like my mind is clearer, and I’ve been resting better. For me, it’s become more than just a beanie, it’s something that gives me greater peace of mind in a world where technology is everywhere. I believe we need to be more thoughtful about how we live with technology, and the Havn beanie feels like a step in that direction. To me, it’s like wearing a little armor in our modern, connected world. I’m happy with my purchase and glad I gave it a try!

The earbud test is the one we'd point anyone on the fence toward. Thanks for taking the time to write this out, David.

The silver lining is doing the heavy lifting, literally. Glad the whole thing went smoothly, Marc.

The qualities of the hat was well explained by the web site, it was easy to purchase on line, it was delivered quickly, and it appears to work as advertised.

I was happy with my purchase and I loved that it shipped and arrived very quickly. I honestly feel a difference with my brain fog. How awesome is that? I’m planning on buying more of your products. Next..a thyroid protector.

Brain fog lifting is the one people tend to notice without looking for it, so that's good to hear.
