Labor Day is approaching, and Walmart is offering deals like the Ninja Creami ice cream maker for $150, which is a discount of $50. This innovative gadget, featured in our Ninja Creami review, mimics high-end restaurant machines and uses a unique technology that Ninja acquired after a patent expiration. The Creami doesn’t churn traditionally; instead, you freeze a liquid base for 24 hours, then the machine blends it with a drill-like mechanism to create soft-serve ice cream, sorbets, and other frozen desserts. It comes with two pint-sized containers for storage and has a compact form factor. While the ice cream it makes is delicious, the machine can be loud during use and creates a softer product than other ice cream makers.
