I bought a fryer De Longhi because I was tired of having to enter a full tank to get out of the waste oil to a funnel placed over the original bottle, itself deposited in a sink with caution because any movement due to arm fatigue or clumsiness spilled oil off With the small tap, it is a true marvel of efficiency. You just slightly tilt the fryer to raise the last drops. Initially I feared two things: that the valve may be leaks and that the crumb deposits that inevitably fall to the bottom do not block the vent system. There is nothing, everything works perfectly. The "scoreboard" is tilted slightly about splashing. I am delighted with my purchase, and I waited a few months of use to comment on it, to give an opinion based on experience.
