1. The bottom stainless steel part falls off all the time, there is nothing to keep it on.
2. The oil does not come out in a fine mist, despite trying different types of oil, it always comes out in a stream first, sometimes I eventually get a mist, even though I pump the gadjet as instructed.
3. The device leaks oil everywhere,if left on work surface after use I find it in a puddle of oil later, not econimical or very nice.
4. I found it fiddly to use, messy and awkward.
