comparing to conairs oil warmer [SEP] i got this product not only because it came with an additional bottle for roughly the same price as the others but the comparation of conairs oil warmer they say this one is better be because of numerous things but one that caught my eye was the leakingit is true that conairs leaks when left on it can heat up the oil inside much better than these type of product for half the price albeit you can only get one oil in thereanyway conairs dispenses and keeps my oil at over f while this one only heats up the oil to about f max even then it requires alot of time to get there moreover it cannot seem to reach the oil in the dispenser so you have to dispense multiple times to get to the warm oil that claim to keep your oil at is only the metal walls that heats up the bottle but the heat transfer to the oil is very badthis product and ones like it is not as good as the one that is half the price although if you do not want hot oil then i guess this one is good for you it does come with an extra bottle
