DefenderShield Laptop Pad for EMF Protection – DefenderPad EMF Blocker Pad That Protects from Heat, Battery & Wireless RF Emissions – Durable, Non-Slip Design for Laptops Up to 17” – Black

I bought this product about 6 weeks ago and have used it daily with my Macbook Retina Pro as well as with other things (iPad Pro, large books.) This product is excellent in my opinion as it achieves all goals which, while may seam simple to achieve to some people, simply aren't when you survey the space of products. First, it is very thin, but also completely rigid and strong. It handles a good deal of weight and never flexes. It is easily stored in my backpack/computer bag and also I keep it to the side of my chair, leaned-up against the side of it. Second, it has a grippy surface on the top so the laptop won't slip-off. You can also put your leather sleeve, if you have one, on top of the defenderpad and then your laptop, that also works well. Every other laptop pad/lapdesk I have used lacks a grippy surface and my laptop fell to the ground a few times-- rules them out without my modifying them in some way to create a grippy surface. Third, it absolutely absorbs heat from the laptop-- folks that are posting here without buying the product and then offer their "expert" opinion are not helping anyone. For my macbook pro, which does get hot, it blocks the heat. Again also, if you have a leather slip/cover for your laptop, you can also double it up. I sometimes do that so my sleeve is nearby. Finally, relative to blocking radiation, I cannot prove that but I can say that the manufacturer has gone out of their way to explain what kind of radiation blocking they provide and the product does everything they promised in all other respects. I'm happy with it, after buying a number of these types of products and giving up on them, this one is a keeper.

I tested this using my Trifield TF2 device and it 100% works as expected. People giving it 1 star or saying it doesn't work almost made me second guess buying it, I'm glad I gave it a shot. People need to understand that this is meant to stop the EMF radiation and heat radiating out from beneath the laptop, to protect your lap. This protects the reproductive areas and that is most important! Obviously this is not offering any shielding for the top or the sides of your laptop, so there is no protection for your hands with this. Using a keyboard and mouse can help with that.The construction and quality of this is great so far, it feels sturdy and the grippy texture stops the laptop from sliding around. The blocking lowers levels significantly. I bought this with the DefenderPad Pillow and they work great together. The Pillow is comfy and adds another 3-4 inches of separation fromt he laptop to my lap, and reduces EMF levels further.Overall using both the pad and pillow I've reduced EMF levels from over 50 mG peaks to about 1 mG peak. I am using a Lenovo Legion Gaming Laptop, but if your laptop is putting out excessive EMF that could potentially change your results. One thing to consider is that EMF is increased when the laptop is plugged in, but even then I am reading less than 2mG peaks under the pad.

I don't use my laptop or iPad without this awesome product! Helps to protect me from EMFs. As a stage 4 cancer patient this is super important! I need to keep my toxic load as low as possible. Thank you for making this awesome product and helping us stay safe in this tech world!

This is one of those products I wish I knew about sooner!I have been using laptops for nearly 2 decades and never given much thought about how much wireless radiation I am exposed to. It isn't until recently there have been much more awareness on the topic that I had to take action. One of those actions is buying this pad.The pad itself is very simple and very good quality. It has a nice rubber surface layer that sits on top of a sturdy tray. The rubber area grips to the laptop and absorbs heat. But if you are someone, like me, who tends to have their knees up it will slip down against your belly. Which is okay, since that is how I typically use my laptop but it still remains on top of this pad and still blocks any wireless radiation from below.As for heat this pad helps a lot. Since it is a flat surface there be improved air flow equivalent to using a laptop on a desk. Depending on how hot your laptop gets you will either feel no heat on the bottom or a small amount that one has to specifically touch the bottom to feel. If your laptop's fans are always whirling and running hot no matter what then I highly recommend to open it up and use canned air. I do this on mines every 6 months and it makes a big difference! This pad will not solve major overheating issues but will greatly lessen the heat has on your body.As for the wireless radiation blocking portion I haven't done any tests since I don't have one of those EMF meter thingies. They are quite expensive, especially a good one! This pad is designed to only reduce wireless radiation from below, which is very important, especially if you are a male. Although I can't say how much it reduces it by what I can say is that after a few weeks of use I do feel less fatigued than I usually did before.This is one of those products that is used daily without thought... until the laptop gets so hot that you are then reminded of it cuz you forgot to use it!
