You don't buy an ice-cream maker like this to save money - it is definitely cheaper to go and buy a lifetime's worth of luxury ice-cream from the supermarket. However, the sheer fun of experimenting and serving your own wonderful concoctions to appreciative visitors is worth every penny. When freshly made, the ice-cream consistency is superb and even fairly plain ingredients can be transformed into something special tasting.
I bought my Gaggia Geletiera about 8 months ago and it has performed well over that time. It comes with two paddles, one of which can be used directly in the unit container and the other of which is used in conjunction with the removable bowl. If you use the removable bowl, you have to add about 25 ml of strong "alimentary" alcohol (some of that vile spirit that tasted so good on holiday but now tastes like paintstripper will do nicely) to the unit container for efficient transfer of heat away from your ice-cream in the bowl without freezing up. There are on-off buttons for the paddle and the chiller unit and a timer dial which gives up to 30 min of mixing time. It's very simple to use, trouble-free and the result is consistently good.
One slight snag is if the timer switches off or the paddle stops because the ice-cream is too stiff, you have to be around to deal with it or the chiller will freeze your ice-cream solid. Getting all the ice-cream out of the removable bowl with the supplied spatula is a little messy due to the cold liquid alcohol on the outside, the embedded paddle of awkward shape on the inside, and the rapid melting of any ice-cream remaining in the bowl after removing the paddle. However, the Geletiera works well and I am very pleased with my purchase.
