Works like a charm.To be fair, I didn't compare this item to any similar. But, am fully satisfied with this product.I bought this pouch so I could safely lock my truck while surfing. . .Work the extra few bucks, IMHO.

Standing literally against the drivers door with the key in the pouch and it won’t unlock the car. So it definitely works.

I reviewed scientific testing of the product which clearly demonstrated how well the bag shielded frequencies across the EM spectrum. The bag is superbly made and fits both keys to our Smart #1.

After returning a prior purchase (signal not getting blocked), I purchase based upon reviews. Blocks signal as advertised as the car will not start up with the fob in the bag. Tried multiple times. Due to it working as advertised, purchases another one for my other fob.

So far it is working great for my car keys and doing what it is supposed to do. We will see how long it lasts.

I tried a few Fob Faraday bags and this one is the only one that I found to really work. I like it a lot, it looks nice, but I will say that I wish it was a size that fits in your pocket.

This wallet blocked the signal to the keys when I tested it repeatedly. We've had a rash of car thefts in my neighborhood but I feel a little better now knowing that my keys are secure from any searching devices. It is pretty heavy duty and very well made. It's a bit larger than what I would like since I only need it for my keys. The only thing I don't like about it is that it's so stiff & rigid.

NFC payment devices are part of my career. So, I look at a lot of different ways to test signals, what enhances them and what blocks them.I tested this using a custom reader that I designed and a standard strength meter looking at 13.56MHz; most common standard for payment chips (ISO14443A/B). The bag did clearly block the signal. I took pictures of the meter inside the bag, but that just looked like pictures of a black hole -- but the meter did not register any NFC excitement. No excitement means no signal to broadcast.The pictures illustrate the signal without and with the bag - same distance from the reader. Not even a flicker at the Tip: This company makes a lot of different size bags -- do pay attention to the sizing for your needs. The bag should exceed the size of your object to protect by several MMs in all directions. If it's too snug, you're going to fight to get it in and out. The bag I tested was good for credit cards, key fobs or similar. There's no way it would fit typical phone (nor does it claim to). Point is to read the dimensions, then add some to make sure what you're securing will fit.The one oddity, and I reached out to the company for a reason -- but they have not yet responded -- is that in my testing, the bag itself (completely empty) was activating the reader. Now, this could just be noise to confuse readers, or something else. My primary concern is that there are any identifying values in that signal. My initial tests did not reveal any (chip UID I was getting was NULL), but I will keep testing. I will update if they have a response.
