Product review (1 stars): Unreliable Cooktop
I bought this item new from Amazon for $254 - and in my opinion, there's a reason this cooktop is much cheaper than almost all other cooktops with sealed burners.

In terms of appearance - it does look nice, with the sealed burners, stainless steel, and continuous grates.

However, I had a few issues with functionality.  The first thing I noticed was that the inner ring of the power burner would not consistently light.  Not matter how many ways I tried to light it, I only got the inner ring to light completely once.  So for the most part, the inner ring would just be releasing gas while the outer ring is burning.

The second thing I noticed is that the other burners - particularly the front simmer burner - do not reliably stay lit.  It's easy to ignite, but beyond that, they usually shut off as soon as the knob is turned from Light to High.  I've seen a few reviews on Amazon with similar experiences - and per the reply, I tried rotating the burner cap, but I still did not get consistent performance.

Bottom line - I see the power burner inner ring issue as a safety issue and an inconvenience, and I see the simmer burner issue as a major annoyance.  Yes, the price is low and it looks nice, but it is simply not reliable.
