DefenderShield DefenderPad Laptop EMF Radiation Protection & Heat Shield Lap Pad - Blocks 5G, WiFi & EMF - Compatible with 17" Laptops, MacBook, Chromebook (Black) | Perfect for Home Office, Travel & Safe Computing

Purchased this product after the purchase of another product that was not getting the job done. The DefenderPad blocks a significant amount of radiation coming from my laptop. This reduction was verified with my EMF test unit.Ill keep it at 5 stars unless it breaks down in the future then ill promptly decrease the rating down to 1 starThis 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!So far, I haven't experienced any heat coming through, however I am not capable of testing how much it actually blocks any radiation.I am a pretty heavy computer user. I run three small businesses and constantly have my laptop with me and it’s usually on. I was discussing the dangers of EMF exposure with a good friend of mine who happens to be an electrical engineer by trade and who has children that use their laptops and ipads on their laps for hours at a time. Of course being very concerned about frequent EMF exposure, he told them not to put them directly in their laps, but they still did. So he went on the internet to find something to protect his kids, but instead found mostly nonsense products. (buttons, pendants, stickers, USB plugs, pads, sleeves and all this other garbage that doesn’t doing anything to shield radiation emissions) He explained to me that when he spoke with any of these companies, he found little to no evidence that their devices actually work, nor could they substantiate their outrageous claims.Being technically minded and having some electrical engineering training I am inclined to believe his experiences and we agreed to help one another with this dilemma. Which brings me to the Defenderpad. I happened to find this product while searching for EMF protection products and suggested that my friend give them a call since he knows more about the subject than I. He didn’t mention that he was an electrical engineer, because we wanted to hear exactly what they had do say. What set this company apart was when he spoke with them, they knew exactly what they were talking about and described believable physics.So we went ahead and bought one and decided to do a little testing together. We mimicked their independent testing environment as closely as possible with the tools available to us by testing the shielding for very low frequencies up to very high frequencies using my friends isolation chamber. I won’t bore you with the details, but we were able to confirm their shielding effectiveness. In fact, our testing showed that they did better than their claims. We also noticed the ambient RF within the room around the DefenderPad was less than the surrounding area (a desirable feature they do not claim). We also looked at their patent and were able to understand why they could shield such a wide range of frequencies so effectively.All I can tell you is that I feel safer using the Defenderpad. I strongly recommend it. Before buying EMF products, please make sure that the companies provide you with some sort of proof their product works. I didn’t realize how many charlatans were out there on the internet before I began this journey and it’s kind of scary.very good quality!I've ordered two of these out of concern about EMI radiating into my body. Whether or not that's founded, I do like the convenience of the product. It's sturdy, doesn't weigh too much, has a nice grip surface and looks good. It's also great at holding back any heat.However, when I ordered a 3rd unit (I have 3 laptops), there were bubbles in the surface material. I sent it back and ordered another but it also had bubbles. So I'm done with this product for now. Maybe in a year I'll try again after they've tightened up their manufacturing quality control.I am happy that this product seems to eliminate the EMR (I have a detector) but as for absorbing the heat, it did well to start with, but no longer manages to keep up with my usage! My husband has one too and he is happy with it so far.Purchased this based on my research and high ratings from all sources. Used it for a few days and then started to feel some heat starting to get hotter and to a point where my mac book would shut down or drain battery super fast. I measured it with EMF meter and the numbers either didn't make a difference or made it worst. Hoping it would work but disappointed on this product! Going to return it and shop for a different brand.This is an excellent Laptop EMF Radiation Shield. I used to have my laptop on my lap and I could feel my nuts heat up. I knew radiation was slipping through. Now my nuts heat up no more and I feel a lot more safer with my laptop on this shield over my lap.I think this defender pad does what it says it does, although it's not easy to know for sure without a proper radiation detector. I do remember feeling a little tingle near my hip when I was using the laptop without the pad and that tingle is gone.One thing I notice though is that the defender pad is quite heavy. I guess there's a reason for it, but the fact is that the weight of the pad plus the laptop makes it a bit uncomfortable after a while. But that's not enough to stop me from using it, considering that health is above all the most important thing and having a radiation emitting device like a laptop (or a tablet) near the reproductive organs for hours and hours every day is certainly something that I want to avoid.Recommended.I bought and returned two of these. Both had air pockets on the upward facing surface making it impossible for the laptop to lay flat, which in turn meant that the laptop moved while typing. They need to stitch up the surface or find better cements. I'm moving on to a different brand.
