Query: Disappointed

I preferred the Lumina ice cream machine that Aldi supermarket sold for $30- seriously it was amazing (while it lasted- 1.5 years). Unfortunately the KitchenAid ice cream bowl is uncovered so doesn't seal the cold in like others do. The paddle isn't great. I have used both plenty of times to make the same custard based Baci ice cream recipe by Nigella and the Lumina aerated the mixture, the KitchenAid did not. In other words, I used to get a lot more ice cream out of the same recipe with the Lumina machine. Kitchenaid makes it flat (like melted and refrozen ice cream). Damn. Im going to get a compressor machine next, hopefully that will do it.
