The words “Fitbit” and “activity-tracking” go together like peanut butter and jelly. Plenty of other companies make wearables, but Fitbit has made a name for itself in the activity- and sleep-tracking world. Considering its solid reputation among consumers, it’s no surprise that people were psyched to hear that the brand was launching its very first smart watch, the Fitbit Ionic.

Available as of October 1, 2017, the Ionic goes for $299.95. That’s $100 more than the Fitbit Blaze, the brand’s most souped-up tracker, but $100 less than the new Apple Watch Series 3 with cellular. When I told my friends I had received an Ionic of my very own to test, they all asked me the same questions: Is it worth it? Should I get one instead of an Apple Watch?

After testing the device out for a few weeks (and testing out the Apple Watch Series 3, too), I can’t really answer those questions for you. I have both an Apple Watch and a Fitbit Ionic, and I actually rotate between the two. But I can give you a good idea of what to expect from the Ionic and highlight the things I really like about it—which are a lot. Fitbit does trackers pretty darn well, and the Ionic is no exception.

Before we get into function, you should know that the Ionic is sleek and comfortable to wear.

One issue I’ve always had with activity trackers is that they’re generally clunky and/or look kinda cheesy. The Ionic is thin, lightweight, and goes with mostly everything I wear (save for a cocktail dress). The watch itself comes in silver gray, burnt orange, and smoke gray, and there are multiple band options. I was initially using a coral sport band, but right now I have a navy leather band that I’m really feeling because it goes with pretty much everything and lays flat against my wrist. I’ve gotten a lot of compliments on my Ionic, and when I tell people it’s the new Fitbit smart watch, they’re impressed.

The week-long battery life is probably my favorite feature.

Having a smart watch that you can go five days without charging is kind of amazing. One, because if you’re like me, you inevitably forget to charge it and it dies midday or mid-workout. The practical benefit is that you can use the tracker for a very lengthy activity—say, a long marathon-training run or a full day hike—without worrying that it will die. I haven’t tested the full limits of its battery (Fitbit says it’ll last for 10 hours of GPS usage), but I’m excited to wear it on my next hike and know that I won’t have to stop it and save my activity data halfway through in case it’ll die on me.

I’ve been able to get a good four to five days out of the watch on one charge, and that’s with using the activity tracking and GPS feature for a workout on two to three of those days.

The watch is also fully waterproof—no “swim” mode required.

I love that I can just wear the Ionic without thinking twice about if I’m going to get it wet. It's waterproof up to 50 meters. (The Apple Watch Series 2 and 3 are also waterproof in shallow water, but you need to make sure to turn the crown to clear out water after.) The watch is made of an aluminum unibody, a fancy word that means that the entire device is made of one piece, so there aren’t any cracks in between parts that will let water in. That makes is a great choice for swim workouts—the swim feature tracks laps and calories burned in the pool. But it also just makes it super wearable for everyday life. I get really sweaty when I work out, so I like knowing my device is a-OK no matter what.

Just as expected, the Ionic has the same great activity-tracking features that Fitbit fans know and love, plus a whole lot more.

With the Ionic, you get all the basics—steps, stairs, distance, calories—plus exercise tracking modes for things like strength training, running, biking, and swimming. The heart-rate monitor and GPS make this a well-rounded device that tracks and compares all your stats to give you a good idea of how you’re performing in the moment and after the workout ends.
