You may not have thought it was possible, but Amazon is still breaking records: A representative for the company told CNBC that its annual sales event, Amazon Prime Day, currently underway, is "so far bigger than ever."

As of Tuesday morning, the e-commerce company's day-of discounts also led to a new sales record for the Instant Pot, a kitchen gadget that works as a pressure cooker, slow cooker and seemingly everything in between.

"Our Instant Pot Duo 6Qt sold out in 19 hours, including [a] 4-hour technical glitch rendering our product unavailable," Robert Wang, CEO of the Canadian company which produces the item, told CNBC Make It Tuesday. "The total volume broke our previous records."

Indeed, the six-quart version of the Instant Pot Duo, which is usually $99.95 but was priced at $58.99 for Prime Day, was only available from third-party sellers on Amazon as of Tuesday afternoon — surprising given that Wang tells CNBC Make It the company's preparation for the event began as early as March. The three-quart version, typically $79.95 but discounted to $59.99, held the top spot in Amazon's rankings as No. 1 seller in the Home & Kitchen category.

The internet-connected cooker gained a cult following in 2017, and today boasts over 1.4 million devotees on Facebook. The secret to creating such a popular product has been seeking out criticism, according to Wang.
