As another reviewer mentioned you need to read the instructions because there are some limitations to this mister. Not genuine limitations as much as caveats to keep you from misusing it. For example, this will NOT work with highly viscous ingredients like bottled salad dressings. Nor will it properly function if you infuse oils in the mister itself (herbs and the such will clog the pick-up tube and nozzle). Plus this has to be hand washed. Since I use only olive oil I clean mine out using a solution of fresh lemon juice and white vinegar, which cuts through the oil and prevents any from clinging and becoming rancid. I find this better than dish soap, which can alter your oil if not completely rinsed out.
What I have been using it for is to lightly mist shaved cheeses. Drizzling oil tends to overwhelm the flavors of some cheeses, such as gorgonzola or ricotta salata. I have also lightly misted toast, which is a nice substitute for butter, and broiled eggplant and other vegetables. Again, sometimes drizzling versus misting is too much, and despite olive oil’s health properties over using it can undo all of the good.
Bottom line: this mister made a believer out of me, While I still drizzle oil on some dishes, I am finding that misted oil has its place in my kitchen too. Also, if you have to infuse oils you can do so in a separate container and use the strained, infused oils in this mister without harming it.
