User Review: For as little as this waffle iron cost, I was surprised at the quality of the waffles it produces. I've used this iron six times now, and each time it makes waffles that are crispy on the outside, tender on the inside. I followed the package insert directions to the letter, washing and drying the heating plates before using, and then brushing the plates with oil (to be more accurate, I used an oil spritzer - please note, if you are going to spray the insides, only use an air pump-type oil spritzer to which you add your own oil [Misto is an example]. Do not use an aerosol nonstick spray like PAM or similar - the plates will become gummy and impossible to clean). I let each waffle cook until the steam that escaped out the sides began to dissipate, which was about seven or eight minutes. The waffles are perfect. I can't recommend this iron enough.
