The strength of the magnet isn't bad at all. It's also thick. It sticks well. The key question is whether it can block the door. I'm worried about what happens if someone wakes up. But considering the price, it's not a problem. Haha.

Protects my car from the slamming doors of the neighbor in the parking space for very little money, how economical and practical it is. Satisfied.

I liked it so much that I bought it again.

Powerful magnet that is very useful when cars are parked close by.

Excellent product! It performs the function for which it was designed!
