Product review (4 stars): Does what it is suppose to do.
I recently purchased a new glass top range and decided I didn't want to use my cast iron skillets on it, so I got this induction burner and it does a good job, but I gave it only 4 stars because when I tried to use the highest setting, it cause the surface to over heat and shut down, so I could only use a medium setting.  Otherwise I think it's a good device.  The pan that came with it is pretty cheap and thin.  Probably only good for boiling water.
