Silent Pocket SLNT Mini Waterproof Faraday Phone Sleeve Dry Bag Signal Blocking, Instant Protection and Security, Protects Against Cellular, GPS, WiFi, Bluetooth, EMR, EMF, Radiation, Anti-Hack

I needed something that fit a bit more than the SLNT Medium Plus phone bag and this really really fit the bill. I work in infosec and am very privacy conscious. After seeing these guys pop up at DEFCON, I was curious about their product. I got their DEFCON branded phone sleeve which fit my phone nicely, but now that I'm attending different things where I'm carrying more connected devices that I'd rather not be connected, I looked around and found this.This fit my headphones, watch, phone, and car keys easily. The dry bag style is great and easy to use too.My testing showed that it was not able to maintain a wifi connection, bluetooth connection, receive GPS signals, or receive calls/maintain a connection to a 4g/5g network. I am very satisfied with the results.

Works and doesn't block.

nice bag for protection from interference with signals. The bag material isn’t flexible leading to the bag to wear in spots over time if folded.

I winded up purchasing one of these after I purchased one of the smaller pouches from SLNT and having a phenomenal experience with it. I winded up putting a key fob in a belt clip case and needed something a bit bigger to drop the case into, so I don’t have to take the fob out of the case every time I want to use a protective pouch. This was the closest thing I could find from them and it works just as well as the first. Outside of placing the pouch directly on the steering column, my car could not detect the key, even sitting in the driver’s seat. It’s exceeded my expectations and I will continue to buy SLNT products for as long as I need them.Only complaint I have (and this is very specific to my particular case and not a fault of the product), but I wish they offered a case/pouch that was half as long and with a slightly wider mouth (maybe 1/2 inch wider), so that I could fit my belt clip case into the pouch with ease. The cases that they currently offer are either too big or too small and I wish there was something in the middle, but again this is very specific to me, so I can’t knock the product for it.Overall, I’d definitely recommend this and anything SLNT has to offer.

I have tried this bag with several different cell phones, and this bag blocked all signals to these phones.I have not purchased a Faraday bag before, so I don't have any base to compare or contrast this with, but it is certainly doing exactly what I bought the bag for. It meets all my expectations, and kudos to the manufacturer on an excellent product.I have also noticed that my battery life seems to improve a great deal when I store a phone in the bag.My only frustration was trying to use the written instructions: "Make sure you roll down at least 4 times and tightly secure with plastic external buckles." (There was no diagram illustrating this "roll down" that I could see on any of the papers included.)Fortunately, I found an illuminating picture on the maker's website; the "roll down" refers to the loose portion of the bag after you slide your phone to the bottom of the bag (much like how you would roll a sleeping bag when you have left something at the foot of the bag.)

Immediately after it was received I placed my phone in bag, had wife try to call the phone from 5 feet away and the call was completely blocked. We tried this several times from different distances and different phones, bag worked every time. Bag appears sturdy, was received on time, and does what it's intended to do. Good purchase.

This bag might offer reasonable water resistance, but as it does not seal, its waterproof claim is doubtful. It offers no blocking or even noticeable degradation of Bluetooth, WiFi, or cellular signals. The test phone was able to connect and play audio over a BlueTooth speaker while in the bag. It was also able to connect and play video content over WiFi, and finally, it received cellular calls with WiFi turned off.

So I haven't hit it with an EMP or a solar flair, but as far as blocking signals - this bag does the trick. Calls, texts and data are completely blocked. Sat my connected smart watch right on top of the bag at the opening (once rolled closed correctly) and it would not connect to the phone. I have not tested it's waterproofing yet, either, but it feels incredibly well made and with quality materials. Definitely recommend. Will hold phone, watch and a key fob if needed.
