Apple began accepting pre-orders for the iPhone 6s and iPhone 6s Plus in the early morning hours of Saturday, September 12, and it appears units are flying off the shelf. The company said Monday that it’s already on pace to beat records set by the iPhone 6 and iPhone 6 Plus last year.

“Customer response to the iPhone 6s and iPhone 6s Plus has been extremely positive and preorders this weekend were very strong around the world,” Apple told CNBC. “We are on pace to beat last year’s 10 million unit first weekend record when the new iPhones go on sale September 25.”

When TechnoBuffalo checked iPhone stock on Saturday morning, it appeared that most iPhone 6s Plus units in the New York City area were still available, save for some versions of the space gray model. By the afternoon, however, almost all units were sold out except for a few variations of the 16GB versions of Apple’s iPhone 6s Plus.

“As many customers noticed, the online demand for the iPhone 6s Plus has been exceptionally strong and exceeded our own forecasts for the preorder period” Apple said. “We are working to catch up as quickly as we can, and we will have iPhone 6s Plus as well as iPhone 6s units available at Apple retail stores when they open next Friday.”

The iPhone 6s and iPhone 6s Plus offer improved cameras, faster processors and a new 3D Touch feature that, it appears, are compelling enough to attract millions of customers.
