It is very good, as strange as it may seem, it actually works. It does what it says. We have tested it.

I bought 2 cases for XCeed 2023 and even though they work for the purpose you buy them, the quality is completely fake. On the 3rd day, the first case tore its seams on the 2 top sides as soon as you open the case.

I don't know how many days it will last until it becomes useless, but I guess not for long...

Update 2 months later: As I had understood from the beginning, it wouldn't last long. Exactly 2 months after using it with the car being taken out once a week or even once every 15 days, the case no longer works and doesn't block the signals, so the vehicle unlocks normally with the key inside.

It is very good proven. Specifically. It has two compartments, in the first external one you have the keyless when you are inside the car so that it can read but at the same time it cannot be copied by an external factor within two to three meters. When you get out of the car to lock it, after you do it, you put the keyless in the second position which is deeper and slightly larger. Then no anti-theft device recognizes it no matter how close it is to your case. The quality is great. I have had it for two years since I bought the professional car and I use it daily, and it hasn't suffered the slightest damage.

It would be convenient if it was a bit larger, so that it can fit a car key along with the keychain and close comfortably
