Shield Your Body - Laptop Lap Pad with SaferBody™, Anti Radiation Shield & Heat Shield Pad, EMF Blocker Laptop Pad for Up to 14in.Wide Device (13.8 x 10.7 inches), Jet Black PU Leather Color

Since there aren't any other reviews here that have reported actual radiation levels and I have a budding interest in EMF radiation, I decided to give a lengthy a/k/a “geeky” review of this product. If you are interested in buying a product like this, I hope this information might be useful to some of you...Like a lot of people, I work with computers all day long. And often, I end up working with my MacBook on my lap. The heat from the MacBook on my lap has always been worrisome, but like most, I got used to it and ignored it. Then, I read that Apple says you're not even supposed to use your MacBook in your lap! So, I thought it was time to do something about that.But, since I'm so used to working that way, I figured instead of trying to change my habits, maybe I would look into a heat shielding pad for my MacBook.During my search for laptop heat shields, I came across the SYB Laptop Pad.Now, there are definitely less expensive laptop heat shields available, but this one also claims to protect against EMF radiation, and I figured it would be worth the extra dollars -- IF it works as claimed. The fact that it's also notably less expensive than the other laptop EMF shields I found on Amazon made it even more appealing to me.I've had this pad for about a week now, and so far, I’m really pleased with the purchase. Since I actually own an EMF meter, I decided to test the manufacturer's claims. Here's what I found:**************************************EMF Shielding**************************************For these tests, I used a Trifield 100XE meter. It's not the best EMF meter out there, but it's a very popular model, and for the money, can't be beat.I took measurements from my 2016 13" MacBook Pro, which has a solid state hard drive.I measured the EMF emissions at two distances: 0" - when I use my MacBook on my lap and 4" - when I use my MacBook on a desk above my lap. I conducted these measurements with and without the EMF shielding pad.It's also important to remember that this Pad claims to shield two types of EMF: ELF-EMF radiation from the power and circuitry in the MacBook and RF/MW-EMF radiation from the MacBook's WiFi and Bluetooth. And, thanks to the TriField, I am able to test both.In testing emissions from the bottom of my MacBook, here’s what I found:1) ELF at 0" (on my lap)Without the pad, I measured 10 mG of ELF radiation.With the pad, I measured 2 mG of ELF radiation.So, by these tests, the pad shielded about 80% of the ELF radiation from my MacBook.2) ELF at 4" (on my desk)Without the pad, I measured 2 mG of ELF radiation.With the pad, I measured 0 mG of ELF radiation.So the pad shielded almost all of the ELF radiation in this test.3) RF/MW at 0" (on the lap)Without the pad, I measured anywhere from 0.2 to 0.8 mW/cm2.With the pad, I measured anywhere from 0.01 to 0.05 mW/cm2.So the pad shielded about 90%+ of the RF radiation, depending on how you calculate it.4) RF/MW at 4" (on the desk)Without the pad, I measured between 0.05 to 0.1 mW/cm2.With the pad, I couldn't measure any detectable levels of RF radiation.Overall, I'd say the manufacturers claims in the listing are accurate as this pad shielded 80% to 95% of EMF radiation emitted from the bottom of my laptop.**************************************Heat Shielding**************************************The other claim the manufacturer makes is that the pad shields "over 99% of heat from your laptop." For this test, I used the Etekcity Lasergrip 800 Digital Infrared Thermometer, so all measurements were taken at the surface - at 0" distance.Without the pad, I measured a temperature of 88.2 degrees.With the pad, I measured 74.6 degrees which was the ambient room temperature.So, I'd say the manufacturer's claims are accurate here, too.**************************************Other Notes**************************************I think the heat and EMF shielding features are the most important for a product like this. But, of course, there are other aspects to consider too.I like the feel of this pad. At a little over a pound, it feels substantial without being too heavy. And it's pretty thin, so it's been really easy to carry with me in my laptop bag.And, while I am not a fan of the reflective top, it is starting to grow on me.I saw one reviewer comment about the edges. That hasn't been an issue for me or my kids. But everyone has their own taste and preferences.Also, my pad hasn't stuck to any furniture or desks or other equipment. I am only 10 days in but the pad itself hasn't "stuck" to anything, at least so far, fingers crossed :).**************************************Conclusion**************************************Overall, I'm very pleased with this purchase. Based on my amateur tests, it seems to do exactly what the manufacturer claims, in terms of EMF and heat shielding. And, it costs about 25% less than the other EMF laptop shields I've seen here on Amazon.If you're not interested in EMF shielding, then there are definitely less expensive laptop heat shields here on Amazon, and I'd recommend checking those out. But if you do care about reducing your EMF exposure, then I can say this product does what it claims.Hope this helps.

Any laptop I've owned has created an uncomfortable 'slow burn' sensation on my legs. Even though I purchased a nice and sturdy lap pad for my laptop, I could literally begin feeling the electric radiation coming from underneath the laptop, through the pad, and into my legs. The feeling would intensify the longer I had the laptop on my lap. Keep in mind this was not simply a hot sensation I was feeling, it was something that I could literally feel driving deeper into my legs and knees, like a slow radiation burn.I finally decided to do something about it and was dismayed at all the wildy swinging reviews of people saying these EMF protecting pads either worked great or were a pile of junk. Even this SYB EMF pad had such differing opinions! After some exhausting research, I decided to go with the SYB pad and I am SO glad I did! It totally took away that slow radiation burn sensation that I have experienced for too long. I merely placed this on top of my old laptop pad so that I would have the best of both worlds and it's awesome! I can still feel warmth after a little while from the natural heat transfer, but it is nothing at all uncomfortable, and the radiating burn sensation is completely gone!I hope anyone else here who has been searching for something to help with the kind of issues I have had is able to find the same relief that I did! It cost me more than I wanted to pay, but it solved the serious problem I was experiencing and I feel like the potential EMF dangers have been greatly reduced by this pad.I went with the black color because others were saying that the pattern wigged their eyes out. While I can see that the pattern does create a slightly holographic effect, it was nothing distracting or bothersome to me. I don't know if the blue color would have been more pronounced and something I would have noticed more, but if you're worried about that, I'd go with the black color. I hope this review helps someone else experience the same relief both physically and mentally that I have received!
