I bought this one as well as two other ice cream makers because it seemed so brilliantly simple - and it is. It is rather like going back in time to the old, traditional way of making ice cream. It is solidly built with no electrical or mechanical parts. Made of stainless steel, so long as it is not damaged by dropping or abuse it will last forever! Nothing to wear out. As far as taking up space, it is about the same size as a small casserole; not very big but it does make 1.5 litres of ice cream at a time; comparable with most more expensive machines and can make two batches before re-freezing. It does freeze rapidly and needs stirring as the mix freezes to the walls, then continue freezing until it is the hardness you want. It is capable of making your ice cream really solid if you want! It does not need to be hovered over but you need to watch the timing, although it doesn't matter if you overdo it by 5 minutes. You do need to mix part way through freezing but it is great fun in a nostalgic sort of way and there are no running costs nor further outlay for worn out parts. If you buy one I guarantee you won't be disappointed and if it stirs an interest in a new hobby and you decide to go for a more upmarket machine as I have, then it is a great back-up, wine chiller, etc. or you could pass it on to someone and give them a hobby. Personally, I will never part with my one!
