After waiting nearly 3 month after buying 2 Fenix 5s Plus and the Garmin index scale for better firmwares, I give up and put these 3 items in my storeroom.
The Fenix 5s Plus has a lousy sleep detection, the basic function virtual partner ist still not fixed (something I need to prepare for halfmarathons), music can freeze during running, I need to wear the watch on the right wirts to connect to my headphones. The index scale is unable to connect and transfer data to the website by normal routers. I am sick of being a beta tester for lousy products.
For now I go back to my Fitbit Ionic (it has its flaws too), my Aria 2 (always connects but has less information) and runtastic which delivers my "virtual partner" in a perfect way. Once more I give up believing one ecosystem fits your needs. I am deeply disappointed by Garmin. 1700 € Bucks for just nothing.
