I have been wanting a Ninja Creami for well over a year, but kept telling myself I didn't really need it and didn't have the counter space. Finally, I got tired of arguing with myself, and when the Breeze model became available at my local Sam's Club, I snatched it up. There are so many online videos you can watch with recipes, tips, and ideas, and those have been very inspiring and helpful. I enjoy having high protein, low-fat, ice cream in the evenings, guilt-free.
There is a learning curve, and you definitely want to make sure to let your pints thaw a little before you spin them if you have a particularly cold freezer, as I do. I always make light ice cream, which always requires a re-spin or two. There are reports of machines catching fire, and this sounds like it's primarily because the pints are so cold that the machine is being overworked and overheats. The other reports are of the blade digging into the sides of the plastic cup, which is why it's really important to shave down any bumps or lumps on the top of your pint before you spin it so the blade is level on the pint. You can rest assured both Sam's and Ninja will stand behind the purchase though, but always good to know the positives and negatives of a potential purchase.
My current favorite flavor combo is chunky monkey where I use an 11.5 oz chocolate protein shake, 3 tablespoons peanut butter powder, 10 g sugar free instant chocolate pudding powder, and a mashed up banana in the pint before freezing. After the second spin, mix in a handful of mini peanut butter sandwich cookies or chopped peanuts if you like crunch and can afford the calories, and you've got a treat worthy of an ice cream shop in the comfort of your own home. If you and/or your family love ice cream and creativity and have a little patience (because you're not going to have ice cream until the day after you unpack this machine) this could be the kitchen appliance you've been waiting for. It would also be more valuable to those who like smoothie bowls, milkshakes, gelato, whole fruit sorbets, and frozen alcoholic cocktails on a regular basis or people who want or need to control the ingredients in their frozen treats.
However, if you're not a big smoothie, sorbet, or milkshake lover or don't have dietary ingredient considerations and are satisfied with the low-fat, high protein ice cream pint flavor options in your local grocery store freezer, I would argue this machine will not save you much money over the long run, as ingredients for ice cream may actually cost more than buying the frozen pint. This may be especially true if you live alone or with other people who don't eat your ice cream pints when you're not looking. If you're on the fence but curious, I imagine in the next year there will be many of these at thrift shops and online resale sites as new small appliance interest tends to ebb and flow. If you're leaning heavily toward owning one, Sam's has a nicely discounted price over most retailers with four pints instead of the regular two. Your biggest issue may be finding one in stock. I haunted the app for a month before my local store had them available, and they were gone within the week.
