You chose a very good lock from Potent. I know Mottura is a bigger and more known company, maybe this is why many people prefer their products. If this one costs half the price of a Mottura, go for it. Mottura may be better, but not "double better", if you know what I mean.
I also saw many CISA, ITALSERRATURE, Cerutti, ISEO while I was there. And many Ingersoll padlocks with proper sized hasps, but it's not an option for a house door.
Here is the thread if you're interested.
Have you considered getting a different one? I mean, a lock that accepts an euro profile cylinder. Obviously you'll need a cover to protect it from snapping or drilling it, but that's how Italian doors are made nowadays. I warn you: it'll cost more...
Good luck and let us know what you chose
