Any range sold on Amazon and Wayfair is going to be chinese parts and pieces, unreliable of the first order, even if "designed" in Italy. You need to move up to a higher price bracket for better quality, better reliability, and actual serviceability.

Designed and manufactured in the hills around the city of Padua, each Lofra Appliance is carefully designed and built with the high-quality standards of a “Made in Italy” brand. -- Catalog

It is also sold on ajmadison.com. The three product lines seem similar so I'd go with the Curva whose closeout price is half the price of the others. It does have many burners but most aren't very powerful (see spec sheet). But at that price it wouldn't be a huge investment so after the two-year warranty expired you could replace it if you found it to be unsatisfactory.

I have a Bertazzoni made in italy it is 18 yrs old I run a catering biz from my home so the range gets a real workout I love it I vae the 6 burner with one of them a wok burner all gas oven which BTW maked much beter pizza and bread than an electric one . A pange that is all gas is always my prefernce . Have you seen the one you are getting/ I would never buy a range online.

You might ask who in your area will SERVICE this if a fail?

Rare is the real need for a 48 inch range. If you are buying for a show kitchen, that's up to you . I'd be wary of any range that can not be serviced locally..

Yes, it's an Amazon world, but I prefer any appliance, come from a local source - including the moment of delivery to the site.
