Fitbit's Charge 2 wearable is now available for $150

One of Fitbit's best fitness trackers is now available globally.

It's been almost a month since wearable pioneer Fitbit unveiled a much-needed update to its Charge and Flex ranges, giving them a bunch of aesthetic and functional upgrades in the process. Customers have been able to secure their orders ahead of the loose "fall" release date but from today, anyone itching to get their hands on the new devices can now do so.

With a bigger display, the $150/£130 Charge 2 allows for a wider selection of watch faces that display more information than before. The optical heart rate sensor can detect how much time you've spent in specific cardio zones and its bigger battery ensures it logs more data before it needs plugging in, which helps it cement itself as the leader in its price range.

The Charge 2 is available with a Classic band in black, blue, plum or teal. However, the company also has a set of $30/£20 accessory bands available -- shipping next month -- that let you mix it up with blush pink, brown and indigo colorings. As usual, the tracker is available via in all supported countries, as well as Amazon, Best Buy and Target in the US.
