Great quality case but needs extra installation pieces for the case to be usable as I already mentioned: I really love these cases. This is my third one and thanks so much for the discount! 😄 However, I bought the universal case as they do not sell one for my specific phone model (Google Pixel), but unfortunately the magnetic sticker does not work because there are three phone cameras on the back so the case keeps on falling off. So the only way I could get it to work is to cut out part of the foam packaging and stick that between the phone and the magnetic sticker with some double sided sticky tape (which I luckily already had) to ensure it can stay attached to the case and still close it. It would be helpful if this company could include those extra things to then make this a 5 star review.

I already wrote a long explanation as to why I'm so upset and disappointed about your product. The magnets did not work. My new phone fell out of the case and landed cement and cracked. It was heartbreaking, but I'm not willing to spend another $800 on a new phone so I am stuck. You need something to cradle the phone inside of rather than just having it loose. Please look at the safe sleeve design as they are the best ones but unfortunately, I have no case for my new phone. With their cases, one can prop their phone on a surface of some kind like a table or a desk without having to hold it like one has to do with your case, and the phone never falls out your inferior magnet design. The magnets don't work anyway, which is infuriating! It's a pain in the ass to take out the phone to take pictures, and I'm still getting burned from the EMF because of your design. Please consider studying the "safe sleeve" designs in order to improve their product immensely. Thank you!

Hi there, we’re truly sorry your phone fell and was damaged, and that the case has left you so frustrated. We understand how upsetting and costly this experience must be. Thank you for sharing your feedback about the magnets, phone support, and ease of use—we’ll pass it along to our team.

I use these in my online business where I see all clients on Zoom. It's essential to have excellent sound quality, both for listening and speaking, and this headset delivers both. By far the best sound quality of any air tube headset I've tried. My only suggestion for improvement would be a longer cord.

How to Choose the Right Laptop EMF Shield

How to Choose the Right Laptop EMF Shield

Why Does Your Laptop Emit EMF Radiation?

Laptops generate EMF radiation from multiple sources simultaneously. The Wi-Fi and Bluetooth antennas emit RF radiation to maintain wireless connections. The cellular modem (in broadband-enabled models) adds another RF source. The battery, processor, and power circuitry generate ELF (Extremely Low Frequency) fields during operation. All of these emissions radiate outward in every direction — including downward through the bottom of the laptop.

Why Laptop EMF Exposure Is Worth Addressing

The reason laptops are a specific consideration is contact duration and proximity. A laptop used on the lap places multiple EMF sources at near-zero distance from the body — directly against the thighs and in close proximity to the reproductive organs. A typical work session lasts several hours, and many users spend 6–10 hours per day with a laptop. At contact range, EMF field strength is at its highest, and heat radiation from the processor and battery compounds the exposure. A lap shield addresses both simultaneously: Ultra Armor+® shielding blocks EMF from reaching the body, while the DefenderPad’s silicone thermal barrier blocks heat transfer to the lap.

How Do DefenderShield Laptop Shields Work?

DefenderShield laptop shields place Ultra Armor+® shielding between the bottom of your laptop and your body. The multi-layer construction conducts, absorbs, and dissipates EMF radiation to block up to 99% of emissions (0–110 GHz on the DefenderPad), including all current and planned 5G bands, Wi-Fi, Bluetooth, cellular, RFID, NFC, GPS, and ELF from the battery. The shielding does not affect your laptop’s connectivity — Wi-Fi, Bluetooth, and cellular signals continue to function normally. Shielding effectiveness is verified by independent laboratory testing.

DefenderPad vs. Laptop Sleeve — Which Should You Buy?

DefenderPad (Standard) — A rigid heavy-duty lap shield with Ultra Armor+® EMF shielding and a silicone thermal barrier. The non-slip silicone top surface keeps your laptop stable; the outer is food-grade polyurethane. Fits laptops up to 17” and is also compatible with tablets and 2-in-1 devices. At 15.8” × 11” × 0.25” and 2.2 lbs, it can slide into a larger laptop bag or backpack. Best for: home, office, gaming, and any dedicated workspace where both EMF and heat blocking are priorities.

DefenderPad Lite — The same Ultra Armor+® EMF shielding in a lighter form factor (14” × 10” × 0.25”, 0.65 lbs) with a textured non-slip vegan leather surface. Fits laptops up to 16” displays. Reduces heat transfer but does not fully block it like the Standard. Best for: travel, campus carry, and users who prioritize EMF protection and lightweight portability over full heat blocking.

Laptop Sleeve — A flexible sleeve with Ultra Armor+® shielding that functions as a 3-in-1: padded carrying case, flat non-slip lap shield, and ergonomic laptop stand. Place the sleeve under your laptop during lap use to block EMF, flip the VELCRO® flap to create a more non-slip surface, or fold the flap into a triangular backrest to angle the laptop for typing. Slip your laptop inside for padded storage and travel protection. Premium vegan leather exterior with neoprene stretch siding. Available in two sizes, for laptops up to 16” and up to 17.3”. Best for: travel, commuting, students, and users who want EMF protection that also serves as a laptop carrying case and stand.

If you work primarily at a desk or couch, start with the DefenderPad Standard — it provides the most complete protection (EMF + heat) with the most stable surface. If you travel frequently and want a single product that shields, carries, and props, choose the Laptop Sleeve. If you would like a simpler, lightweight and more affordable option, choose the DefenderPad Lite. If you need to cut your laptop off from all wireless signals for privacy or EMP protection, choose the Laptop & Tablet Faraday Bag.

What Makes DefenderShield Laptop Shields Different?

Three specific engineering choices separate DefenderShield from competitors. First, Ultra Armor+® blocks the widest frequency range available in a consumer laptop shield — 0–110 GHz on the DefenderPad, including both ELF and RF. Most competitors block only a fraction of this range. Second, the Standard DefenderPad combines EMF shielding with full thermal radiation blocking in a single product, eliminating the need for a separate cooling pad. Third, all shielding claims are backed by independent laboratory testing with published results.

Laptop EMF Radiation & Heat Shields against EMF Radiation FAQ

No. The shielding blocks EMF radiation emitting downward from your laptop — it does not interfere with Wi-Fi, Bluetooth, cellular signals, or any aspect of laptop performance.

Yes. The DefenderPad Standard fits laptops with displays up to 17” and the Lite fits up to 16” — both are also compatible with tablets, iPads, and 2-in-1 devices such as the iPad Pro and Surface Pro.

The Standard DefenderPad blocks both. Its silicone top surface is thermally resistive and prevents laptop-generated heat from transferring to your lap. The DefenderPad Lite reduces heat exposure but may not completely block it, especially with high-power devices. The Laptop Sleeve provides moderate heat reduction through its multi-layer construction.

Both use Ultra Armor+® shielding and block up to 99% of EMF radiation (0–110 GHz on the DefenderPad). The DefenderPad is a rigid lap shield optimized for stationary use, with full heat blocking (Standard). The Laptop Sleeve is a flexible 3-in-1 case that functions as a lap shield, carrying case, and ergonomic stand. Choose the DefenderPad for maximum protection at a fixed location; choose the Sleeve for portability and versatility.

Yes. Both the DefenderPad and Laptop Sleeve are free of heavy metals (including lead), PVC, BPA, BPS, and other known environmental contaminants.
