1 month, around 25h of use, I'm really liking it! Been through sunny days and pouring rain and it endured well; GPS syncing is fast, normally 30s-1min; App is easy to use, syncs fast with the device then straight to Strava, enables to export a FIT file as a backup plan; Easy to update firmware, customize screens, and use is practical while riding; Sensor syncing is only through the app which is bad, should enable sync from managing the device (like models from other brands do). Could use some improving: beep sound is too loud and only option is to turn all off, offering volume adjusting would be good; Info on the screen, 'elevation gain' is one of the main metrics while riding and if you could offer to show that would be great; It comes with handlebar support which is very practical, it's right at eye direction looking down, the support clamps directly, without a hinge like similar products from other brands, it's a bit scary at first but it didn't broke, it clamped well.
As described, prompt shipping and arrived rather fast , a bit more than 1 month. Setup is easy with the app, after registration. The clamp for the handlebar is too large for my bike. I will have to patent something.
