I purchased this unit a number of years ago on the basis of the oil filtration system and the ability to keep it clean in the dishwasher. I used it four or five times and was very pleased with the ability to drain the oil and keep the used oil in the fridge. About the fifth or sixth time I used it, it started making a loud bubbling noise, and when I opened the top, oil exploded all over the kitchen and my face. (fortunately I wear glasses and wasn't badly burned.) I think I called T-Fal and didn't get any satisfaction. I subsequently saw a recall notice for a JC Penney fryer that looked identical, but TFal continued to deny any knowledge of such a problem. At some point I tried using it again (on the porch), and it wouldn't go over 300 degrees, so maybe I just had a bad unit. I might try another one.
