Vector Luna Review
Vector's OS is quite barren in terms of features and apps and is no match for Android Wear or Apple's watchOS2
As mentioned in the introduction, one of the defining characteristics of the Vector Luna is its compatibility with all three of the major platforms—iOS, Android, and Windows Phone. This puts it in a rather unique position when compared with the majority of smartwatches on the market, which are generally limited to just two operating systems at best. All you need to establish contact with any popular smartphone, therefore, is Bluetooth and the VectorWatch companion app.
Unlike other smartwatch operating systems, the Luna's interface and feature set are pretty unimpressive and will require some getting used to if you're accustomed to Android Wear, for example. The basic premise of the system is that you can add up to 5 watch faces, any one of which different from the other, and navigate them by using the up and down buttons on the side of the watch. Depending on the watch face (of which about 20 are available in total), you can add different “streams”, which are just tiny widgets. For example, you can add a calories burned counter, steps, date, distance, stocks, weather, and that's about it. Some watch faces support up to 4 or 5 “streams”, but you can delete any of them to simplify the interface. Overall, these all look pretty utilitarian and dull.
Critically limited app selection
Whenever notifications hit your smartphone, a solid white line will encircle the outer bounds of the Luna's display, and the watch will vibrate. To explore notifications, you press the crown once. Pressing it a second time dismisses the notification. As long as you tick a setting within the companion app, dismissing a notification on the Luna will also clear it from your smartphone, which is great.
Only 8 apps in total are available for the Luna, and there's so little free space on it that you'll have to delete some of the default Vector apps (Timer, Alarm, Stopwatch) to install them. We tried the BBC and ESPN apps, both of which serve news titles that aren't even displayed in full if too long. You can't read the actual articles on the watch, nor is there a way to jump on your phone and start viewing them, making us wonder what the point is. All apps are essentially yet another watchface to cycle through and you navigate them using the up and down buttons on the side, but need the circular crown in the middle to enter them. Long press returns you back to the respective watch face.
Performance and Battery life
If you're coming from Android Wear or Apple Watch, you'll be blown away by the battery life.
But if you're like us, and see smartwatches as more of an accessory that simply expands on the timekeeping paradigm with some neat extras, then the Luna is one way to go. With its industry-leading battery life and compatibility with all three major smartphone platforms, it's uniquely positioned. On the other hand, we don't quite like the pixelated display, nor the fat bezel around it, an we can't say it's very competitive in terms of pricing (starts at $299). For those reasons, and again—despite the incredible battery life—we can't rate it higher than far more feature-rich offerings like the Gear S2.
