Strange. Their ad makes you think they have something special when in fact they have what every other door manufacturer has. A good old sectional door. Lots of good American companies out there.

I would never buy anything mechanical or electrical from another country if I could buy it here. Not only are standards very different in other countries it is often impossible to get approval for things you would think didn't need approval.

There certainly are a lot of good custom door manufacturers in the US.

I think the best is Hahn

None of them are a bargain.

I am just laughing.
While 'sectional doors' may be a breakthrough in Italy, they are the standard in the US and have been since after WW2.
This is how every run of the mill garage door in the US works.
What an astounding breakthrough.
