SYB Shield Your Body EMF Blocker Phone Case, Powerful Radiation Blocker for Cell Phone, Durable Anti Radiation Cell Phone Case, Black, XXL, for Phones Up to 4.33-Inches Wide (11 x 19 cm Pouch Size)

I tested this with my own Erickhill RT-100 EMF tester and it only made a slight difference. EMF spikes when you receive a call or text. It is extremely low if any while nothing is happening so it needs to be tested while receiving a call. This maybe how they got the test results they did. This is a waste of money for EMF protection!

I have good news and bad news but here is a thorough review with metrics and a video.TL;DRMagnetic fields are reduced by an impressive amount.Radio frequencies are reduced by about 80% when measured from the back of the sleeve.Claims:"Use a power density meter (not a gauss meter, tesla meter or electrosmog meter) to measure the shielding effectiveness of our Phone Pouch, which blocks up to 99% of radio frequency (RF) & microwave (MW) EMF radiation emitted by your mobile phone."There are 3 issues with electronics:Electric fields, Magnetic fields and Radio Frequencies. All of which are harmful and are EACH part of what makes up the so-called "radiation" from electronics like our phones.The video:The video I uploaded shows that the pocket does in fact block about 90-99% of Magnetic fields which alone makes for an effective product. Note: the recommended exposure limit by most governments is around 2.5 mg (milligauss) see emfs.info/limitsRadio frequencies (RF)For some, having a working device while still being protected is the goal. I'm not an electrical engineer but I have learned that RFs are either 100% contained in a Faraday cage-type environment otherwise they bounce around. This is what the second part of the video shows. RFs are heavily reduced when directionally measured from the back of the sleeve which is also fantastic for people who want their phone to work while gaining some protection.RFs are not blocked up to 99% in real-world scenarios. However, they are reduced by about 75-85% directionally which is a lot to expect from a sleeve that still allows phone service.All EMFs are at a minimum while on Wi-Fi only.Cellular transmission, specifically data transmission, cause extremely high amounts of EMFs.

I bought four of these pouches as Christmas presents, two large and two extra large, two purple, one blue and one black . They can be attached to a belt which could be useful. I don't know about the radiation aspect, which is really why I bought them, but they are good quality and if they do what they say in that respect, they are excellent. They were very well received presents by all. The packaging was good with a very informative leaflet enclosed. A good quality product and I am pleased I have it even if just to keep my phone safe.

Comoda da infilare nelle tascheA breve testerò con rilevatore di frequenza

une bonne protection pour les chocs. Pour les ondes c'est à vérifier

I am very satisfied with this shield. I use it every day.

exactly what i expected and seems well made

A soft, good-fitting pouch for my iPhone 6+ that claims a 99% defection of EMF radiation. I purchased this pouch on Amazon after reading about EMF radiation online and getting concerned about it.So I searched Amazon for solutions, as I routinely carry my iPhone in a leather hip holster that affords no EMF protection. This pouch, and the Pong case, were the solutions. The Pong case is a minimalist case that deflects 67% of the radiation away from the body. The SYB pouch defects 99%. The Pong case fits with the iPhone 6+ in the SYB XLarge Pouch nicely. So I opted for the double protection.By the way, it is recommended that, if you do wear the phone somewhere on your body, that you do so with the screen facing towards your body as both the Pouch and the Pong case defect radiation away from the screen.Even if you didn't wear this pouch on your hip or belt, it is a nice holder that could fit in your purse or man-bag as well. If worn on a belt, it is carried vertically as it is opened at the top. Not a problem as it doesn't fall out, but I would like to see the folding flap like the smaller models have with an option to carry it horizontally as well. Carrying the rather large 6+ vertically has me placing it on my belt more towards my back so it doesn't get in the way when I sit if it moved to the front of my body on the belt.This product earns my 5-star rating also because of its excellent customer service. Emails answered quickly, informatively, and courteously. I greatly appreciate that as it is there if you need it. I only had questions on how to wear it and other products they offer and should offer and they were there and responsive. By the way, register the product online and you get a lifetime warranty. Nice. Thanks SYB. And also BTW, I have not received any perks to do this review.Do your do diligent research and consider this product as part of your solution.

Given the use after a number of weeks, I must conclude that it is nonsense to purchase this. It is not convenient to keep sliding your mobile in and out of this soft cover. My advice: it is better to buy a hardcover case.

This Faraday shield pouch is unique. It is widely known that the energy emissions from a phone are omni-directional. This pouch has the shield on only one side, so it can block all the energy emitted from the phone from going toward and affecting your body. That means if you put your phone in the pouch, insert it into your pocket, and you orient it so the shielded side faces your body, the emissions are deflected away from your body. It does however still allow the phone to receive texts and calls. Additionally it has a handy fabric belt clip, so you can carry it on your hip.

Why did you pick this product vs others?:Perfect for Samsung 25 Ultra. I just guessed it would fit my Galaxy 25 Ultra and it fits perfectly. 

Para Xiaomi MI 11 es algo justo. No lo cubre totalmente. Si no encoge me sirve. 1 cm más seria idóneo.

I am trusting that it works, but can't review on that aspect.I always wear my phone in my bra. Just diagnosed with breast cancer. I have read it's not true that our phone in our bra can cause it. Anyway, decided to err on the side of caution. This is sooo helpful and comfortable for me
