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.

The photos below should provide some data and help dispel some of the ridiculous rumors and reviews that I've read about this product. In a nutshell:1.It has NO direct effect on the laptop whatsoever from a speed standpoint. Someone said it caused their laptop to run slow.2. It eventually gets warm, so as a heat shield it's just so-so.3. It DRAMATICALLY reduces EMF. Look at the pictures. A steel cookie sheet reduces EMF by 2/3, from about 300 MG to about 100 MG. This knocks it down to 3, a 100:1 ratio.4. The plastic cover has rough edges, so you won't want to wear shorts when you use it. I'm actually thinking of returning mine for another model for that reason, but the dramatic EMF attenuation does offset the discomfort. NOTE: It works equally well with the holographic or the rubber side up. And the sharp edges curve slightly upward with the rubber side up, so it's more comfortable that way. It's how I'm using it right now.5. RF and electric fields are basically unchanged, but then unless you live in a cave on a mountain somewhere, RF and Electric Fields are everywhere. The E-F reading in my photos are random. They fluctuate due to local cell towers, appliances, etc. But the 1 or 2 volts/meter you see in these pictures are insignificant compared to the 240-430 that I get near 5G small-cell stations.Now, will it prevent medical problems? No one is really sure. I'll be 68, and all my life I've been amazed at how companies just put stuff out there without any clinical trials or studies and then wait to see if people start developing problems. It doesn't matter if it's medical, or electronic, all that matters is the money. I'm old enough to remember Thalidomide. Researchers have discovered that 3G (2.45 GHz) can cause diabetes in lab rats. The 5G rollout is the latest unknown. So who knows whether or not laptops and/or cell phone radiation will cause problems. This pad won't stop RF signals that reach or emanate from your laptop. Just EMF. EMF supposedly causes a decrease in fertility with humans. A problem for young people, not so much for me. BTW, EMF also radiates toward your body when using a laptop, and it's almost as bad as it is from the bottom.I might buy a different brand that's known to be more comfortable, and then compare the two. If I find a softer pad that reduces EMF down to 10 mg or lower, then comfort will prevail. But this model REALLY slays the dragon.FOLLOW-UP: I tried a more comfortable brand that features a "vegan" leather cover, but it was less effective than a plain cookie sheet. So I sent that one back.BTW, the scan rate with my little EMF-390 is slow enough that I was able to take photos within a few seconds after making changes to illustrate how dramatic the reduction is. You'll see it in some of the photos.You might notice a little "dip" in some of the photos of the graphs. That's the result of my lifting the laptop up to insert the pad. During that period, the EMF drops to near zero.Stay tuned for more info.MORE INFO: I should mention that the readings shown above from my EMF-390 should be taken as relative values or indicators - no doubt a lab-grade, calibrated device would show much different numbers, but the dramatic differences would be the same. A German lab recently conducted tests with such equipment on 4 or 5 of these handheld EMF meters, including a rather expensive model whose manufacturer claims that it is the most accurate. According to the German lab report, it was only slightly more accurate than ones like the one made by Cornet, which appears to be similar to the EMF-390 that I used. But that lab stated that none of the ones tested were accurate, nor did they live up to their frequency response claims.I'm in the process of testing the meter that I used for the above review against a lab-grade spectrum analyzer with a range of 100 Hz to 26.5 GHz. I'll post the results on my web page, and also on Amazon under QC EMF-390.w3afc

Wi-Fi router is under our TV only 10 to 15 feet in front of us, so I decided to test the RF levels about 10 feet in front with my TriField TF2. It was reading 0.3 to 1.2 mW/m2 regularly with intermittent quiet periods. I can't even believe this is considered OK...I just tried this shield out by placing it in the shelf vertically in front of the router, and when I tested levels the fluctuating results were about 1/5. During the quiet periods it was almost 0, while the noisiest I saw (briefly) was just over 0.2 mW/m2.I still get perfectly good Wi-Fi reception while directly lined up with the path of this shield. You don't need this level of energy to get good reception 20 feet away. It also doesn't affect anything else in the house because the line of sight where I have it lined up points to our kitchen which is not far. The rest of the rooms are through walls behind and to the side. I think it's a great idea to box in your radiation source is to reduce the amount of energy being transmitted through at your house. This stuff is horrible and that has been proven time and time again in multiple studies. It's entirely unnecessary to broadcast at levels that are 10 to 15 times higher than what's considered "safe", at least by European standards.Also, as a sidenote, if you have an iPhone and you use Siri, when you press your home button to activate Siri or say "hey Siri", for the duration of the listening/interaction. Your phone will be transmitting RF at about 100 times the "safe level". I'm not entirely sure why, other than the fact that Siri is a synchronous connection when in use, but that still seems pretty ridiculous.

Very quickly - Package arrived very promptly - as arranged - Well put together - Have been more comfortably using it since the moment we opened the package and did a few quick checks with our reader - from each location around my old MadBook Pro RF levels appeared to be decreased to varying degrees - and the decrease in heat felt on lap is considerable -No time / ability to further test the unit with my setup - which is key of course - but have quickly looked at the materials with order - the ebook and directions to test the unit - all are helpful - direct - so a great unit - as described ~ with tests so far
