Once again, the first thing you'll notice about the Fitbit Inspire 2 is that it looks a lot like the ones that came before it. The company says the tracker's plastic case has been streamlined. No to mention that the outdated side button has finally been removed. Instead, you'll have an easy-to-use capacitive button. You'll also get longer battery life this time around. The Fitbit Inspire 2 should last for up 10 days depending on usage.

Speaking of the design, the Fitbit Inspire 2 comes in three colors, including Lunar White, Desert Rose, and Black. If these colors don't tickle your fancy, you can choose from other first-party or third-party Fitbit Inspire 2 bands. If you're not a fan of wearing your tracker on your wrist and prefer to use it as a pedometer, you can use the clip-on accessory.

When you buy the Fitbit Inspire 2, you'll receive a one-year free trial of Fitbit Premium.

As you might recall, the previous Fitbit Inspire models were available in a heart-rate version and a standard version.

This means you'll need to carry your phone around if you want to track your route when exercising. You also won't have an altimeter, so your device won't track floors climbed.
