Why you'll love it: The Fitbit Charge 2 lets you track your workout in real time on its bright, easy-to-read screen, plus, it has a heart rate monitor and sleep tracking.

Fitbit's best fitness tracker is the Charge 2 with its bevy of activity tracking features, good-sized screen, and decent price point.

The Charge 2 has dedicated functions for recording a wide range of activities, including running, cycling, cardio, and strength training. Its large display is perfect for tracking your results in real time while working out. I could quickly check my heart rate to make sure I was within the range I wanted to be, and see how far I was into my workout with the timer. You can also use the button on the side to go through menu options.

When I'm not running, I'm a big fan of interval training and HIIT (High Intensity Interval Training) workouts, so I was happy to see that the Charge 2 has an interval timer option. It also lets you pause and resume workouts, and if you do forget to start an activity or workout it can automatically detect an activity session and start monitoring it.

The Charge 2 does offer connected GPS via your smartphone for walking, running, and hiking while you're outdoors so you have the option to track your distance in more than just steps. While there were times that the connected GPS wasn't 100% accurate, it was nice to have the option at least - especially as a runner. It should be noted that while the Charge 2 is water resistant, it isn't waterproof, so this won't be going in the pool with you.

If you're looking for built-in GPS, a waterproof device, or even more advanced features, you'll want to look at the Ionic, but if not, the Charge 2 is a great all-around fitness tracker that covers the necessary bases. In addition to tracking steps, the Charge 2 also measures stairs climbed, calories burned, resting and active heart rate, and offers in-depth sleep tracking.

With the sleep tracking, it was interesting to see where I stood on average with other women around my age within the app. If you're feeling stressed, this tracker also offers breathing exercises to help you relax.

The battery life of the Charge 2 lasted me about 6 days, even when I had notifications for texts and calls activated.

Although it has a bigger screen, this tracker still manages not to be overly bulky, even on my small wrist. I found the wristband to be extremely comfortable, and love that Fitbit offers a ton of different colors and interchangeable band options.

Most reviewers love the Charge 2, especially those who upgraded from the original Charge HR. This reviewer also notes how easy the app is to use, and appreciates both the feedback and motivation that the device itself gives.

Pros: Comfortable design, lots of color and band options, large display, built-in heart rate monitor, in-depth sleep tracking, advanced workout features, real-time workout tracking on screen, long battery life

Cons: No built-in GPS, not waterproof
