Product review (4 stars): Beautiful, simple, well supported product
this review is mostly about the repair service I've recently received from Bertazzoni, but also for the range itself, to the extent that my older range is the same as the current model.  I bought a house that came with the 2002 version of this Bertazzoni range.  Back in 2002, Bertazzoni sold what is now called its "Master" line under the brand name "La Germania", not Bertazzoni, but that was just a naming/marketing thing they did for a year or two.  In 2013 I got very good service, and was able to find the correct parts for my eleven year old "La Germania" range, but because of the name confusion ("La Germania") I had to email Bertazzoni directly in Italy at Service@Bertazzoni.com, rather then starting with the normal Bertazzoni service network in the US.  They bent over backwards to help me get my range fixed, and I can't praise their service enough.

I love the 5 burner arrangement because I get a very high output capable burner (up to 15,000 btu) but without needing to have space for a 48" range.  The large burner has flame in a small ring around the inside, and also a larger ring further out, so heat is delivered to the bottom of the pan much more evenly than typical burners that have flame only in a ring around the outside.

The range top and burners are very easy to clean because there are no gaps for junk to fall between.  Usually I just wipe the stainless steel, but when I need to clean the round burner heads (where the flame comes out) that's also easy (they just lift off).

The whole thing is built solidly, and designed simply, so it's reliable.  My oven thermostat needed to be replaced after eleven years, but the part is still available, and only 120 bucks (very reasonable for the most complicated part on the thing).  I've never broken a knob, or had any plastic parts break (it's all steel).  It's simple design is a plus for me because of reliability, but if you want fancy electronic oven controls, timers, etc. you might think it's a minus.

It's beautiful.  I'm more of a function over form guy, but if I cared a lot about how my range looked, I'd still be very happy with this one, it really is beautiful.  I like that nothing about it looks cheap.  It looks/is solid and high quality.

I can cook on it easily, clean it easily, and it is reliable; for me that's 95% of what a range is supposed to do.  It's not perfect, but I find its flaws to be minor.  The oven door gets a little hotter than I like when baking at high temperature.  The oven is wider than I need (so maybe burns more gas than a smaller oven would require) and isn't as tall as most ovens I've used.  I've never needed it to be taller, but it could be a problem some day, so check the dimensions and be sure you're okay with the oven height.
