Familiarity: I've put it through the wringer
Fit is awesome. The band is supple and moves with your wrist. Navigation is easy and quick, even with gloves on. You can customize the activities, endlessly! This is the best part of the watch. There's every activity you can do, and a ton of useful data. It does basics, like steps and caloric burn. I think the calorie algorithm is on the generous side based against my Garmin and Apple Watch. Another amazing feature is the auto sync to Strava. The Suunto App is useful and clean. It give you sleep performance as well as when you are feeling fatigued. I was surprised with how accurate this was, and it's a smart feature to have. Lastly, excellent battery life! However, one caveat (see below).
Let's start with the fact that the metal rim around the screen scratches. It could be a little more rugged in that regard. The main problem I am having with the watch, centers around its glitches. After three days the watch was stuck in the download mode. Nothing worked and ultimately I had to let the watch die. After that, I was back on track. However since then, the steps tracking has stopped and sleep data is missing. Another development has been battery life, which has suddenly gone down hill. After a full charge, 10 percent of the battery was gone in hours of just normal use (time mode, no activities) so at this rate it is around 3-4 days before it dies. This is a far cry from the battery life it started with. Lastly, the Moveslink App is how you update the watch. Yet, even that is glitchy. Connecting the USB cable no longer works so that you can add your watch. I am hoping that there are fixes coming soon because I love all of the features this watch has to offer and can see using it for all of my activities. It's perfect for backpacking, rock climbing, cycling, gym workouts ... you name it. Suunto makes quality products and I know they will work out the kinks.
Should you buy it? Yes. Despite the glitches (which I believe will be remedied) you can not find a watch on the market with this much to offer as far as custom sports modes. Not many watches can cross over and give you as much useful data as the 5.
