Review on PELEG DESIGN Oiladdin Stopper Aladdin by Tara Greene

Very nice idea but not really good. The threaded end is just a few millimeters smaller than it should be, so doesn't fit snugly in the neck of large oil bottles - half the time you pull the lid to open it, the entire device just pops out of the bottle of oil. the hole as a whole is also too small, hence it pours much slower than one would expect. Probably most annoying is that the mold still drips a bit after you stop pouring, so it's messier than using a single bottle of oil. The end result of all the little hiccups with this stopper is that it's actually faster to unscrew the cap on a bottle to pour and then close it again than to open that cap and wait for it to flow and then stop dripping.
