as a dad with kids and always on the go in la, i was worried about car thefts, so i did some research and picked this up. it's a simple case that does what it says—blocks signals when closed. i slip my key in, and no more worries about someone hacking it remotely. it's very effective, and i appreciate the peace of mind without any fuss. just a tip: make it a habit to close it right after use, or it's useless. overall, a solid diy-style solution that's affordable and does the job well :)
- Pros: it's pretty good at blocking signals, so my car keys feel safe from sneaky thieves. very lightweight and fits in my pocket easily, works with most keys i have, which is handy for daily use.
- Cons: you have to remember to keep it closed all the time for it to work, which i sometimes forget, and it might not fit every single key type out there, but most likely it does.
