Wondering if anyone has any first hand experience with this gun?

I know they were made by various makers, Z H, and F Sarriugarte, I have a double 10 gauge from each of these makers, the Sarriugarte seams like a better quality gun than the Zabala, but I put the Zabala through hell, and it just keeps working, so I really can't say they are not strong guns.

Anyway back to the Brittany, are they well balanced?
Do they seam strong?
How did/do you like them/Yours?

Thanks
