I really like some of these products and to try them I purchased the extra insurance in case of needing to return an item. The ball cap is excellent, and the headphones work. Sadly, the in-ear pieces seem to contain rubber or latex of some kind. I also tried the overhead earphones. They're nice, but very chunky, so much that my teenagers hate the style. The website didn't work for returns and I am having to call them to try to return the items we didn't like. It also says we have to pay return shipping... hopefully not since I paid $38 for the insurance, which would surely cover return shipping. The products seem very effective, but their customer service and accessibility needs improvement.

Hi Stephanie, We are sorry to hear these didn't work out for you and that you had some trouble with our returns portal. We are happy to help process a free return for you. We have sent an email to clarify which items you would like to return. Warm regards, The DefenderShield team
Absolutely love my new phone case. Finally a product that offers a magnetic design that holds my phone super secure inside but also allows me to remove it easily. Much much better than sticking to phone case. And my phone never falls out. Thankyou so much 💓

Hi Rosalindae, Thank you for your kind words! We are happy to hear you are enjoying the phone case! Warm regards, The DefenderShield team
A company’s true quality becomes apparent when things don’t work out perfectly. Here, the issue was handled exceptionally well: quick response, direct communication, and refreshingly low bureaucracy. Highly recommended.

Hi Jason, Happy to hear you got your products quickly and are enjoying them! Warm regards, The DefenderShield team
If I could, I would give 0 stars this company fake? I checked their product, especially phone case by certified radiation meter. And it shows that radiation comes through. When I send them this proof they said, it's my meter doesn't work. Lol.They also never answered the phone.Because this is absolutely fraud organization, they sell fake product never, ever by this product.

Hello, Thank you for sharing your feedback. We are sorry to hear that you are dissatisfied with your experience. Regarding our phone lines, we are sorry we missed you! Please note that our offices were closed for the holidays to allow our team to spend time with their families, which may be why we were unavailable to take your call. We stand behind the integrity of our products, which are backed by independent lab testing to ensure they meet the shielding specifications listed on our website. Testing EMF shielding can be complex, as many consumer-grade meters require specific settings or environments to provide an accurate reading of specialized shielding material. We value our customers' trust. If you are not satisfied with the product, you are more than welcome to return the case for a full refund within our 30-day return window. Please reach out to us at [email protected] so we can provide you with the necessary return instructions and resolve this for you. Warm regards, The DefenderShield team
UPDATE: Great customer service. I did receive a call back from DefenderShield, they sent me another replacement and made sure it was intact before they sent it out. They also issued me a refund. Whatever you do, do not purchase the Defender Shield EMF Radiation-Free Air Tube Over-Ear Headphones. My first Defender Shield EMF Radiation-Free Air Tube Over-Ear Headphones broke in under a year when the earphones fell off. My second one broke in the same exact spots in less than 2 weeks. I put in a warranty claim and they literally shipped me a headset that was already broken in the spot where the other two had broke. So I email them and they send me another replacement and, guess what.........that's right, it too is delivered already broken in exactly the same spot. They clearly have a manufacturers defect and it seems like they have no interest in fixing it. Their quality control is obviously crap. They are the Boeing of the headset world.
