Should I buy a Ninja Creami Breeze or a used Creami Deluxe?

It usually comes down to price, capacity, and risk tolerance.

• Buy the new Ninja Creami Breeze if you want the safer purchase: no hidden wear, a fresh machine and container, and the peace of mind that comes with buying new.
• Buy a used Creami Deluxe if you want the larger 24-oz pints and the extra Deluxe programs like Slushi, Frappe, and Frozen Drink, and you can inspect it carefully before buying.

I’d lean Breeze for most people unless the used Deluxe is meaningfully cheaper and you really want the bigger capacity and extra settings. With a used machine, check that the pint/container, lid, paddle, and locking mechanism all work smoothly, and assume warranty coverage may be limited or gone.

If you mostly make treats for 1–2 people, Breeze is the simpler buy. If you often make bigger batches or want the Deluxe’s extra modes, the used Deluxe can be the better value — as long as it’s in excellent condition.
