スマートキーを入れるのに購入しましたが電波遮断は完璧でした。信用できる商品です。

宇宙人に勧められて買いました。電磁波測定器で計測したら、ちゃんと遮断されていました。 ハッキング防止の為購入しました。買ってよかったです。

調べてみましたが、電磁波、遮断されないですね。

とてもしっかりした作りです。購入して満足しております。

Works. My phone seemed invisible to wifi, Bluetooth and 5G. Does its job as far as I can tell. Seems well made. The Velcro closure is easy to use. Very fast shipping.

Funciona perfectamente. La señal del dispositivo se pierde nada más introducir el dispositivo.

well constructed and durable. Looks good for overseas travel. Tough too. works for phone, credit card and car key fob great product.

Perfect it works perfectly. No signal when phone is in the bag

I own three of these. They are far better (mil spec) quality than are my other, smaller Faraday pouches. I use the smaller pouches for both my car sets of keys; to avoid electronic spoofing of my car's RMC rolling Unlock/Re-lock codes. Though WHY anyone would want to steal my worn-out-looking, 22 yr old car would be beyond me. Its deceptive, though, as the car has low mileage, an engine in good shape, recently new tires, new front brakes… and such like. However, ‘they’… have broken into my car twice in the last ten years its been sitting on the street 24/7, out front of my place. Not trying to actually steal it… just intent on stripping out anything loose inside (and some items not so loose). I use one of these bags, to simply fold over my cell phone, at night, it lying on a shelf, near/adjacent my head; NOT actually placing the phone IN the pouch, and then sealing it fully closed. This way, EMR from the phone is blocked from radiating in my direction, but enough signal can reach the phone, that it remains fully conscious/functionable. I also occasionally carry my phone in this bag… while traveling in my car. So Google can’t trace my movements; if/when I actually DO care about that. Mostly… I don’t. But these Faraday wallets/pouches VERY well serve that exact purpose… if one really does care. I have two of these mounted to the arms of my wheelchair (one each). One is configured so as to shield my near thigh, pelvis, and body, in general, from EMR from the phone; which I usually carry in an plastic, armored case. That I then have mounted to the underside of my wheelchair’s right armrest, via two pairs of powerful NIBs. NIBs being NeodymiumIronBoron supermagnets. I prefer the stronger N52 ratings for all my NIBS; which I have over 6000 of. About five thousand of them are little, cylindrical NIBs ¼” long, ¼” in dia., with an axial, 1/8” ID hole through the middle. Combining these with my 800 ½” dia. and my 500 5/8” dia. steel ball bearings… allows me to construct interesting, what I have so-named… ‘magnet sculptures’. The most complex one I’ve made weighed over 42 lbs. And contained several thousand of the little NIBs, along with near all the steel ball bearings on hand. It was QUITE the geometric concoction!! I bought all these NIBs over a period spanning almost two decades. NIBs aren’t particularly cheap; even smaller ones. The third of these particular Faraday bags, I have superglued in the same place, on my LEFT wheelchair arm’s cushion. In the past, because these arm cushions wear out so fast… I’ve usually bought them six at time; for my personal stock. I now anticipate buying no more of them, however. Alright, maybe ONE more pair; for the day the ones currently on my wheelchair actually DO wear out. After… the ballistic nylon has worn to the point of no longer serving this physically protective function. By which time I'm sure the Med Beds will have been released... and I'll no longer need the chair... anyway. :-) I had noticed just how tough the ballistic nylon of the Faraday wallet covering my right wheelchair arm’s cushion (and shielding the phone) IS… and how well it essentially DOES NOT WEAR; for any/all of MY personal, practical purposes. I bought the first one of these nearly three years ago. I was so pleased with it, that I bought the second one a month later. Thus far… there literally is NO apparent wear. On any of these three Faraday Wallets/pouches. So I bought the third one just to cover the nearly-needing-replacement state of the chair’s left arm… that had not had the protection of the ballistic nylon these last three years. I have a Samsung Galaxy S22 Ultra; a pretty large cell phone, as such go. Cased in my case bottom, its 7” x almost 4”. A bit larger when in the full case, top and bottom, snap-closed together. The top of the case is the part attached to the wheelchair by the larger NIBs; the bottom of the case is the part attached to the back of the S22. Enabling me to simply snap the phone into place, as I join the two case halves together, there, under my chair’s arm. Even when the phone is fully armored – and thus already substantially thicker, two medium/large NIBs still reside on the case’s back – plus a rotating spring clamp, for attaching to a belt; making it about a half inch thicker, yet. Nonetheless, the phone, now noticeably larger, still quite easily slides in & out the wallet. These Faraday wallet/pouches are incredibly tough, will last many years; and are quite effective at their job of isolating the phone and it’s EMR. I could hardly rate these bags any higher. Buy one, if it fills your need. You’ll not regret it!
