The oil filter is more a gadget than the utility: it is far from enabling to dispense with "manual" filtration ... This is the reason the star removed in my notation: I expected better efficiency even though I suspected it would not be a miracle solution either.
For storage, it is not too bulky and the handle folds inside the tank (by cons, we must take care not to fold the oil if left inside the tank between two fried because the handle folds under the oil level: small design error I guess ...)
In short: an entirely satisfactory device, I recommend.
