We knew anticipation for the Xiaomi Mi Band 3 was high, but Xiaomi's wearable device partner Huami has revealed it managed to sell 1 million units in 17 days - which is impressive stuff.

The new fitness tracker, announced at the end of May, builds on the incredibly popular Mi Band 2 with a better screen, improved workout features and NFC for making payments with your wrist.

The Mi Band 3 hit the million mark much faster than its predecessors, says Huami, with the Mi Band 2 taking two months to hit the big 1M, and the first one twice that. It certainly proves a stickiness here, and shows that Apple's not the only one blazing a trail in sales numbers.

The Mi Band 3 comes with a heart rate monitor that now runs all day, yet the battery will still stretch for 20 days. It's 50m water resistant too, with a larger to display better for showing notifications and new features like Xiaomi's weather forecast widget.

NFC is one of the biggies here, but there's no guarantee this feature will be available outside of China. In fact, the biggest question now is when we'll see it in the west. The Mi Band 2 made its way over, so we'll hopefully see the same this time, especially with it selling so well in China.

Another reason it's doing so well too is that price. The basic Mi Band 3 costs 169 yuan in China, so about $26, while the NFC version is 179 yuan - about $30. Now you understand why Xiaomi is doing so well in wearables, huh?
