I can not keep the bennie on. It's very slippery and even tried to use bobby pins to hold it on. The bottom rim is to thick for the pins to hold it on. So unable to wear it.

A beanie that won't stay on is useless, so let's fix it rather than leave you with it. Email [email protected] and the team will swap you into a style that stays put or refund you, your call. Sorry Wendy.

Washed on delicate, cold water, laid to dry...blanket is not even when folded, uneven edges.. really bad. Very disappointed considering the cost!
Response from HAVNOct 13, 2026
Cold delicate wash and laid flat to dry is exactly right, so this is a fault in the blanket, not in how you washed it. Send a photo to [email protected] and we'll replace it. Sorry Doris, that's a lot of money for something that came out of the wash wrong.

well, I emailed you back to tell you. I only wanted to order one hat at the discounted price and I received two hats and was charged full price on one of them and i never heard back from anybody. I do like the hat and I ended up gifting the other one, but I did not intend to buy two of them specially painful price when I had a 15% off
Response from HAVNOct 14, 2026
Email [email protected] with "Trustpilot, double order" and we'll refund the second hat and the 15% you should have had on the first. Glad the hat itself is a keeper, sorry about everything around it.

I've only worn it a handful of times and the stitching is coming undone. Its rather tight which is not bad in itself but it is too long. It either pulls down past my eyes or im stuck with loose hat on top of my head. I also feel like it was way to expensive for the super thin peice of fabric I got. I understand that I'm paying for the silver lining but the other hat material is just a scrap of fabric.

Send a photo to [email protected] and we'll replace it or refund you. On the fit, the hat is cut long on purpose to cover the back of the head, but if it's sitting over your eyes it's the wrong size and we'll sort that in the same email. The outer fabric is kept light so the silver layer can work without turning the hat into a helmet, though none of that excuses the stitching.

I didn't see any improvement of my sleep. I thought the sleep cap would provide better sleep.

Email [email protected] and we'll refund you. If you want to try one more thing first, the cap only covers your head, so most people see the bigger change once the phone and router are out of the bedroom too.

I received my EMF protective blanket and paid about $200 for a thin, flimsy product that they probably paid $25 to make. Compared to the Defender shield product which I bought, the HAVN product is a rip off. Defender shield s blanket has a cover and is so much stronger and better made. Hope they will allow me to return it.

Thanks for the honest feedback, sorry the blanket didn't live up to what you expected. Good news on the return: we've got a 30-day money-back guarantee, so you're covered. On the product itself, every HAVN blanket is independently tested to IEEE-299 standards, so I'd genuinely like to understand what fell short for you. If you're open to it, that feedback helps us improve. Either way, we'll make the return easy. Sorry it wasn't the right fit.

I do notice a shift when I wear the beanie, but after wearing for awhile it gives me a headache - making my problems worse, not better. The lightweight beanie is not stylish in real life, and not enough stretch. I’m pretty sure they filter their bad reviews out, because I reviewed the product honestly and it did not show up. So all items on their website show 5 stars, so don’t believe the hype! Can’t trust any of these online companies advertising on social media anymore. They will also say there’s a sale, and then increase the prices LOL. Overpriced for sure, I ordered other stuff on Amazon for way cheaper and liked it.

Hi Sandra, appreciate the honest feedback! The headache isn't a typical reaction and might be due to the beanie being too tight. Email us at [email protected] and we'll make it right, full refund included if the beanie isn't working for you. On the reviews — we don't filter them. Our reviews run through Yotpo, which is third-party verified. I unfortunately can't find any review for the lightweight beanie with your name on it. On pricing, our WaveStopper fabric is independently lab-tested to block 99.97% of EMF radiation. Cheaper Amazon options use a fraction of the silver content and don't publish test results — different product, different price. Either way, reach out and we'll sort this out.
