Product review (4 stars): Think it theough before you buy.
I wanted one of these (sleek flat stoves) forever.  I thought it would be the solution to all my problems as far as keeping my stove clean.  But boy was I wrong!

This thing gets food "seasoned" onto it like it's nobody's business.  It does it in seconds, before it has time to cool so you can wipe it off.  It does it with anything and everything.  Like, If you are boiling potatoes, god forbid they should boil over (which seems to be a ritual practice for my family), the water will instantly evaporate and what you are left with is caramelized on potatoes starch.

If you get hot sugar on it or leave an empty pot heating, it is possible to warp the glass.  I use cast iron which I used to season right on the stove - can't do that anymore.  I am actually afraid to use cast iron at all, since I could potentially drop it and crack the glass.

It is impossible le to regulate temperatures since the burner stays blistering hot once it is hot because, well, it is glass and that does not cool as rapidly as metal.  So if you bring something to a boil and then want to lower it to a simmer, it will continue to boil for longer than you'd expect.

Someone in a comment had said that this is not for someone who cooks a lot and my first thought was "psh, they just don't know what they're doing!"  But now I know what they meant.  If you want to run your kitchen like a restaurant chef, then this is not for you.  If you are a fast cook, this is probably not for you.  This is for patient people who take a lot of care not to spill or shake their pans on the stove.

But now I'm stuck with this, so I will deal.

I still love the flat surface, though.  I wish there was a way to incorporate that and the sturdiness of an electric or gas stove.  That would be perfect.

All that said, this works just as good as other glass cooktop and it looks pretty when it is kept clean (may the force be with you).  I also love that it is not digital but has knobs.
