Safety!
There has been a spate of serious thefts of BMW cars, locally, over the last few months, and the criminals are getting away scott free!!!! One of the bosses, in the company I work for, had 3 BMW cars stolen from his driveway overnight. This is not petty theft, this is serious crime! When I heard about this incident I immediately looked up protection of key fobs, because the thieves didn’t need keys - just computers to steal the cars. I bought this box because when placing the key fobs (the part that remotely unlocks the car) in this box, anyone planning to steal a BMW or any other valuable car, cannot remotely do so. My car would never be stolen because of the make, but it would be devastating to my son who’s BMW is his pride and joy and his ability to get to work. Please buy this...it’s an essential....or a similar product....it is an essential in this modern world. Technology is so clever these days...one aspect a help the other a hindrance. This Faraday box is a marvellous item xxx

Nice little box.
This is a great box, definitely blocks the signal from keys, but it’s not very big. It will easily fit a couple of key fobs in, but not if you have lots of other keys attached. Looks nice, and does the job well.

Blocks the signal from reaching the car
Cover of the box does not align properly. I have to push at the cover from behind to close the box. Lovely product - box itself looks good

Really good value for money and definitely suits the job it was designed for.
Tested against my car and fully blocks signal when in box even within an inch of the car. A tiny weak spot at the top of the box where the signal can go through, but chances of this being a problem are next to none. Nice design too, intricate latch mechanism.

It works as advertised
Delivered on time, overall good quality finish product, and it works, I can just about fit my Tesla RFID Keys in the box and when closed and walking up to the car and holding it up at the entry point, the doors did not open. It would be beneficial to provide the internal dimensions and guidance on what will or will not fit e.g. Car Keys yes and how many, which/how many phones, etc.

Superior quality product well made
This item was much better quality than I expected. The faraday box was sturdy, stylish and mostly importantly, functional. I would definitely recommend to friends and family wishing to shield their remote care keys from would bb thieves when at home.

Works well.
The box works well, large box fits 4 sets of keys (just). The box catch lasted 2 days and broke, this doesn’t affect boxes ability to work.

Peace of mind
Good value faraday box - well built and the locking mechanism works well. I already have faraday pouches for my 2 keyfobs and both sets fit in the box (with the pouches). I’ve tested the box by my vehicle and keyless entry doesn’t activate so it definitely works. Hopefully it continues to offer protection, and I’ll probably test it every week or so as I’ve read that protection for these sort of products can suddenly fail, but for now it definitely provides peace of mind.
