Mr Cat's birthday is coming up, and he's extremely difficult to buy for. He has, however, expressed an interest in a milkshake maker (after buying himself a milkshake when we were out walking over the bank holiday). I've looked online, and can only find smoothie makers or milk frothers. Does anyone know if there is any real difference between a smoothie maker and a milkshake maker? Mr Cat doesn't have particularly sophisticated tastes, and is more likely to go for traditional frothy milkshakes made with syrups rather than the more healthy smoothie option - would a smoothie maker froth the milk? Or would I be bettter just buying a milk frother? I quite like the looks of the smoothie makers with taps on.
