DefenderShield EMF & 5G Radiation Shielding Blanket - Viscose Made from Bamboo and Cotton - Signal Protection Cover for Beds, Couches, Pregnancy, Babies (Throw - 36" x 35")

It blocks as per description, I used a tool to measure and under the blanket the waves are much less

Seems to work. I use it quite often. especially when putting laptop on my lap. When I am not using it, I feel radiation and my kegs burn.

Love it.

It works! I tested with my Trifield EMF meter. Perfect for laying on the couch and on the airplane while pregnant.

For the past 10 years, I have been using a 2.4 GHz wireless trackball keyboard. Three months ago I was diagnosed with bladder cancer. This style of keyboard is the best input device for my use of my computer. There are no long-term studies done on RF energy and its effect on various human tissue. I am 80 years old. I bought the DefenderShield EMF Radiation & 5G Protection Blanket specifically to block the radiation coming out of the bottom of the keyboard. To test the efficacy of this keyboard, I folded the fabric blanket over in half and then in half again. This created a four-layer blanket. I placed the keyboard as seen in the photo below and then folded the quad-ply blank over the top of the keyboard in order to fully seal the keyboard in a four-ply sandwich. I pressed on the fabric to activate the keys. They worked fine I could easily type various characters without any problem with the keyboard sealed in the blanket. Here is a sample; cvnjmn m,. mn,.m,. mn//. The product did nothing to block the RF signal coming from the keyboard. I am totally disappointed that the DefenderShield EMF Radiation & 5G Protection Blanket did nothing resembling "Anti-Radiation" "Protection." I am keeping the board to use as a liner for the copper EMF screening that I bought today. Aside from the fact that it is expensive and does not perform as advertised, it is very well made and is soft to the touch.

It works! I tested it. So I bought another one for my son. It is a bit small but good for the protection. Just be careful with washing/drying! My mom accidentally put in dryer & now it doesn’t work. They should put huge CAUTION label informing customers not to machine dry!!
