I have owned dozens of others which have all stopped working (when used with oil) within a few months. I use those cast-off no longer thereafter useful oil misters filled with thinner liquids such as vinegars (usually works). If this stops working as an EVOO oil mister I will post an update.
Someone else mentioned the lid pump being uncomfortable to pump??? I disagree. It has a slight angle which I find more comfortable and as I said I use it a lot as well as other pump type food preps like salad spinners so am performing the task often. Anything that relieves pressure from my wrist is welcome.
