I chose to give this product a 5 star review for two reasons. First, the shipping was expedient with no damage to the product. Second, this product works EXTREMELY well. I have purchased non electric tortilla presses in the past with very minimal success. The tortillas always came out lopsided and too thick for my liking (also the traditional hand operated ones could only be used to make corn tortillas). With the heat this device provides, the home cook can now have fresh flower tortillas in no time. The home cook can make any size tortillas they want based on the weight of the dough ball. I prefer my tortillas to be smaller so I used around 20 grams of dough to make the sized I wanted. A 50 gram dough ball (about the size of a golf ball) will easily fill out the entire press with ease which is 7 & 14/16th inches in diameter.When using this product allow the device to preheat for at least ten minutes. At the same time preheat your pan you are going to use to cook them. I used a ten inch Calphalon hard anodized aluminum fry pan; the tortillas never stuck and came out beautifully. I do have two comals but decided not to use those initially. The device really does par cook the tortillas and you do need to finish them off in a fry pan, skillet, or comal to finish cooking. I used all purpose flower and have not yet tried whole wheat flour or masa flour.I like the fact that this device is reasonably priced for the job it performs. Other devices like this are much more expensive and geared more for restaurants than the home cook. With this product the home cook can crank out fresh tortillas in no time. using more than one pan will help speed up the process because the press itself will flatten and par cook tortillas very quickly. you will be slowed down by the 45-60 seconds it takes to completely cook the tortillas. I would estimate that someone could make 1 flour tortilla every 5 seconds just using the tortillas press (not including time it takes to cook in the pan).When using the press, place the dough ball down and close the lid. press down with the handle for about three seconds, release, then press down again for about 5 - 7 seconds. Steam will come out and you will hear a hissing noise as the steam escapes. Open the lid and use a wooden spatula to take the tortilla off (they will be hot) and place in the pan to cook...it is that easy.I would recommend this product to the home cook or to someone who sells tacos on a taco truck. This device takes up very little space. By using this product, you will be able to take good homemade tacos to another level and make them great. I will be trying to make corn tortillas tomorrow (26 June 2014) and will report on the success or failure of the attempt. On another note the plug is geared for use in US homes at 120 volts and not the 220 volt outlets that are used outside the United States.
