I've been using wearable activity trackers long enough to know it can be a bit of a lottery when you buy a new one. This was my first look at a Suunto product and I chose it based on the features it has, the reasonable price and the generally favourable reviews it has received here and elewhere. The watch did not, however, live up to expectations, nor even come close. The most immediately noticeable issue is the user interface which is just horrible. Navigating around the menus is counterintuitive and frustrating and you quicky find it doesn't quite do what you want/expect in many cases. You can argue that given a bit of time you can get used to anything new and learn to live with things that are not quite as you would like, but to make that effort first requires that the device actually functions correctly and records data reasonably accurately. Sadly not so for the watch I received. Heart Rate measurement was consistenly low, even if I warmed up as suggested prior to starting an activity. Since many of the calculations the watch makes as part of it's activity tracking functions use the heart rate data, constantly incorrect measurement means these calculations are no good either. This problem alone would be enough for the device to fail, but it has another trick up its' sleeve - it cannot count steps. I really do not know what it counts, but the numbers it comes up with bear no proximity to actual steps counted manually. During a power walk it registered roughly every other step. That's right, half! During a whole morning of gentle walking which should have been in the region of 18000 steps based on the distance covered, it eventually clocked 10000. No matter how much or little money you spend on an activity tracking device, the one thing before anything else it should be able to do is count steps reasonably accurately. Lesser ones are prone to counting movements other than steps in the total, something you can take measures to mitigate, but there is no hope if your device cannot even tell when you're walking at all! I know there is every chance I got a duff one. It happens. But unfortunately I don't spend this kind of money to put up with duffs. I returned it for full refund and went back to my Garmin which still works fine.
