Despite middling reviews, the Apple Watch got off to a solid start Friday, with U.S. pre-orders topping one million, according to shopping data firm Slice Intelligence.

Some 957,000 people in the U.S. ordered an Apple Watch on the first day the smartwatch was on sale. And the average buyer bought 1.3 watches, according to ereceipt data from 9,080 online shoppers. That would suggest more than 1.2 million Apple Watch units were ordered on Friday.

On average, Apple Watch buyers spent $503.83 per device, Slice said.

Some 62% of buyers opted for the low-end aluminum Sports model, which starts at $349. About one-third bought the stainless-steel Apple Watch starting at $549.

Most buyers (71%), choose the larger 42 millimeter case vs. the cheaper 38 mm version.

So the average Sports watch buyer ended up spending $382.83 while the steel model cost an average of $707.04.

The very expensive Gold model apparently didn't have enough U.S. pre-orders to register with Slice data.

The Black Sport Band was the most popular, accounting for 49%. 16% chose a White Sport Band with about 10% favoring the more-expensive Milanese loop.

72% of Apple Watch buyers bought an Apple product such as an iPhone, Mac or iPad in the last two years.

Friday also was the first day that the the new super-slim Macbook was available, with some 48,000 sold, Slice estimated. Some 43% of Macbook buyers also preordered an Apple Watch.
