Mengshen Blocking Anti Hacking Protector Wireless Review

I'm not entirely familiar with RFID blocking, but I've seen it on the news and I know it's good. I have these portable charging cases and they are great for that. Good size, not big and bulky. Robust material that lasts!

I ordered 3 of these. They would be too small for most smartphones on the market today. I managed to fit my whole bunch of keys in with all my keys but it's tight. It would be nice if you only had a few keys or if most keys were kept on separate lanyards. It also seems to be made out of cheap and flimsy materials so I'm not sure how long it will last.

I purchased this item to prevent the fob's reinforcement from being hacked and I can confirm that it blocks the signals coming in and out of the fob. It is made of faux leather (plastic) with an internal signal-blocking fabric that closes and secures with Velcro. It seems well done. It is small enough to be easily carried in your pocket or purse. It's too small for the iPhone 6, and I suspect it's too small for most other modern smartphones, especially when in a case.

I bought this for my keyless remote because thieves used the signal booster to break into my car. This works great to block the signal. I put the key fob in my pocket and the car won't open when I'm standing next to it. The hardest part is putting the keys in my pocket as soon as I get home. Better to keep them in the freezer. I recommend this product to anyone with a remote keyless entry as a thief with a signal booster can easily access your car at any time. You must use it consistently for…

Holds a new keyless fob for my son's new car fairly well. It's plastic, but it blocks the transmitter signal perfectly. Easy to put/remove from pocket. NOT for a full set of keys - and not for a cell phone - make sure you look at the dimensions and add the thickness of your phone if that's the use you have in mind. Good for traveling, especially. If your room is too close to your car without blocking the signal, your car may be left unlocked. This must be supplied with the key ring for all new…

I put the key fob in the inside pocket, went to the car - but the car remained locked, the key fob is not visible. It is necessary to put the key fob in the inner pocket where it is surrounded by a gray conductive fabric. Putting the key fob between the lining and faux leather case provides no protection, no signal blocking. Without test equipment, I can't tell if it offers enough protection to survive a hacking attack with a powerful, sensitive transceiver, but it's definitely better than…

This didn't help to block the RFID. The reason I'm giving it two stars instead of one is because I didn't use it for its intended purpose (blocking cell phone signals) but used it as a car key. . . While I'm skeptical based on my experience, I assume it can work for a cell phone (maybe there's a difference between "RF" and "RFID" signals, or maybe a key that fob transmits does a stronger signal than a cell phone?). If you're considering buying this to protect your car key so others can't access
