As Harrison Ford’s character tried to prove in the woefully underappreciated The Mosquito Coast, the one thing that defines modern civilization is our ability to create ice. And while many refrigerators have integrated ice makers, you might still be living with a model that requires you to fill freezer trays with water, like a caveman. If that sounds like you, a countertop ice maker might be the perfect small appliance. Right now, the Costway Portable Countertop Self-Cleaning Ice Maker is priced at just $105 when you apply promo code CNET63321 at checkout. That’s $10 off the current price of $115 and the lowest price I could find for any countertop ice maker in this class.
