yes, I use a baby bottle warmer too. Infact if you look in the ellisons catalogue, their oil warmer is infact a baby bottle warmer, they don't even remove the stickers telling you how to warm a baby bottle from them. I know this for fact, as I got a place I worked for to order one for me, we sent it back.
I got given my warmer.
they have a thermostat on it, so you can dictate the exact heat. I have a lovely ceramic sake bottle that I decant my oil into and put into the warmer.
