I have the KitchenAid ice cream maker attachment. I haven't used it as much as I would like, but it's been a lot of fun when I have. But yeah, you have to store it in the freezer before using it, and it's big, so finding space can be a challenge sometimes. Have you been storing the ice cream you made? What have you stored it in if so? I never quite found anything that was working great the few batches I made.

I bought these from Amazon. A little plastic wrap over the top then put the lid on. Perfect for sharing - my wife took a pint of our latest batch to work today to share with coworkers.
My only advice with the prefreeze attachments is make sure they get VERY frozen first. The key to creamy ice cream is as colder an environment as possible, and unfortunately among the three major machine types (pre-freeze, ice & salt/old fashioned, self-refrigerated), pre-freeze tends to have the most trouble. Self-refrigerated and ice/salt have more ways to take heat away (self-refrigerated is obvious, ice and salt you just keep adding more, plus very cold to start with). With pre-freeze you’re stuck - it better be cold enough at the beginning to make it all the way through the churn, otherwise you’ll end up with soup and can’t use the canister for another 24-48 hrs.
I like my Nostalgia one as it’s ice/salt. If I ever upgrade it will be to a fancy self-refrigerated. Unfortunately those will set you back $200-400. I need to prove to myself this is more than a temporary obsession before I drop that kind of coin haha.
