You Shipped it to the wrong address
You Shipped it to the wrong address. I put in the correct address when placing the order and after payment, it was shipped to an old address from an old order months ago. How does that happen???? Not happy.

This is the third phone case, the first 2 clips broke. Being that you changed the clip style i figured maybe improvments were made. Unfortunately ,for the price charged for this case, i was highly disappointed with the product and the changes.

Tried them and they're M.
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.

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

Order: SO- 589922 In July 2023 purchased a pair of emf tube headphones. First set we received had split tube cover and were returned and we received a second pair. Within about 18 months the second pair were faulty. The flex became 'mangled' and 'crumpled' yet there was NO mistreatment of the headphones. They were literally plugged in and removed and when not in use, placed in a drawer; they were not even folded. Very poor quality headphones that split with twisted flex. Very poor, and extremely patronising customer service. Essentially, they provide poor quality product at a premium price.

Hi Anne, Thank you for sharing your experience with our EMF tube headphones and for your feedback regarding our customer service. We understand your frustration with the issues you've encountered. We'd like to clarify a few points regarding your purchase and warranty. Your initial purchase was made through one of our authorized dealers in July 2023. The first pair of headphones received exhibited a manufacturing defect, which was promptly addressed with a replacement. Your second pair of headphones, unfortunately, developed a 'mangled' and 'crumpled' flex after approximately 18 months of use. We understand you believe this was not due to mistreatment. However, our warranty, which covers manufacturing defects, is valid for one year from the date of purchase. Your correspondence was received in December 2024, nearly five months after the warranty period had expired. The photos you provided showed a twisting of the cord, which, while not affecting the functionality of the headphones, is typically indicative of wear and tear from storage or use over time, rather than a manufacturing defect. Our warranty is designed to protect against defects in manufacturing, not issues arising from normal use. We strive to provide high-quality products, and we regret that your experience did not meet your expectations. We also regret that our warranty limitations led to a negative customer service experience. We value your feedback and will use it to continually evaluate and improve our products and customer service processes. We appreciate you bringing this to our attention. The DefenderShield Team

Contacted DefendeShield customer service about a return request as their product actually blocks Apps from working properly. A latent issue found after their 30 day return policy. Will NEVER buy or recommend their product EVER.

Hi Stuart, We understand your frustration with your experience with our product. Our return policy has a 30-day window, and unfortunately, your order was placed on 03/01/2024 putting it well outside of this time frame. While we appreciate your feedback, it's important to note that our EMF shielding products are designed to minimize EMF exposure without interfering with device functionality. We value your feedback and will use it to continue improving our products and services. Warm regards, The DefenderShield Team

Three months after purchasing an EMF Defendershield earplug for $75, the unit stopped working. I contacted Defendershield for assistance, but they only offered to replace the unit if I paid $8.99 for shipping. This is unacceptable, considering the item became defective within a short time frame. As a result, I am highly dissatisfied with Defendershield and would not recommend their products to anyone.
