This contained 5 different sizes of signal-blocking bags. They have a strong and heavy feel, with a slightly rubberized texture. The closure is made of strong hook-and-loop strips that require some force to open.I tested these with 3 methods:First, I connected my Bluetooth headset to my phone and started playing a video on YouTube, which requires use of both Bluetooth and wifi signals. Within about 10 seconds of closing the bag the video was stuttering and pausing. Shortly after it stopped entirely, and then my headset announced that it was disconnected. This was consistent for all the bags, although for some reason I had to re-close the middle-sized one 3 times to get it to work.Next, I used a Tile device to find the phone. It found it perfectly within about 10 seconds when the phone was outside the bags, but once it was inside it completely failed to find it.Finally, I simply tried calling the phone. The calls did not come through.Maybe I can next try putting a payment card in the smallest bag and seeing if "tap to pay" works. If I try that I'll update this review.I'd say the bags did a great job, although I'd suggest making sure that the closures are firmly done. Overall, these are great signal-blocking bags which I can recommend.

Oh, these are nice. They have a nice rubbery feel to them, so slightly grippy on the outside. Each bag (except for the cell size bag) seems to have a special attachment feature and the laptop bag has both an attachment D-ring and a Nylon handle strap. Most important of all though is that they work effortlessly at blocking signals. Since they require a tight one full roll-and-a-half to attach the Velcro they will almost guaranteed create an RF shield to effectively blog signals. You would really need to try or damage the mesh for this not to work effectively.-I put my Key fob and keys into the smallest pouch and my car would not unlock even with the pouch held up to the door.-I placed my phone into the cell-sized pouch and attempted Find my Phone. The phone did not ring until I opened up the pouch and started pulling it out. Definitely more effective and reliable than the single fold envelope-style fraday wallets.In photo, Pixel 9 XL for size reference.
