Product review (1 stars): glass shattered completely after boiling a pot of water!
this is really a 3.5 but does not deserve a 3 hence the 4 stars.  The range is very nice, but upon arrival the left burner would not light with the piezo spark so I have to keep a barbeque type lighter next to the range when I use both burners.  I also wish that it would produce a little more flame.  the ring that separates the flame from the bottom of the pan is a little high in my opinion.
Does it work?  absolutely.  Takes longer to boil a pot of water in the current config but I may try to find other rings that will lower it a bit.

Update!!!

Had been reasonably happy as you can see from the above review. However, I boiled some water this morning and turned everything off including the gas source as I always do.  Approximately 5 minutes later I heard a crash and rushed to the kitchen to find that the glass top of the unit had completely shattered with some very sharp pieces on the floor.  The glass is mostly intact however it is completely shattered similar to what a car windshield might do but without the little square safety features.  These are jagged pieces!  I tried to contact the manufacturer but no answer on their 909 area code phone
