Document: Recommended to my daughters. It's versatile and I bought it to make fudge--easy to control the temperature which is important.
It is non stick, temperature static. We had used it for many years. There is no splash due to its high wall and it also means difficult to scoop out the food,
My mother-in-law recommended this product to us. I heats quickly and holds a constant temperature. The size is perfect for the two of us. And it's easy to clean.
Used to twice so far for french fries, and can not seem to keep the temperature up to brown the fries. The fries taste great, just no real cooked color or real crispyness.
I love my little Presto Cooker, it is so great to deep fry stuff in, because of the temperature control. It will keep the same temperature and that is what you want when you are deep frying, so things won't be greasy.......
I am so happy with this item that I could kiss the chinese that made it. Actually it was a breeze to get running and the temperature is right on as indicated. I will be using it as a fryer only.
This item (my second) has a great temperature  control, and,being from the South, my grits and gravies, and so much more come out perfect. Perfect for soups and slow stews. I Highly recommend this item.
The rest of the element never got anywhere near this temperature. This explains why the oil never got hot enough.I did return it and am now I am looking for something that will do what it says.
I bought this item after doing research showing that this item is a great deep fryer. I filled with oil and it cooks great! It is slightly larger than a fry daddy and has adjustable temperature. works great
(the split peas, particularly)  Well, I put them on an hour ago when I started this review. Awesome Power - they are done!Addendum:  As I said, it *was* difficult to get the temperature setting just right.
Answer: Goes up to 400 F; excellent fryer.
