Hello, thank you for your review. I'm sorry you've run into some shortcomings. Below I send a statement directly from the manufacturer.
1) GPS accuracy:
Weather can affect GPS accuracy in general for all devices, but in most common situations this effect is minimal. GPS location can also be affected by where you are, in the forest or indoors the signal is weak. The watch uses GPS, Wi-Fi and BTS networks, but under certain conditions the location can be at least approximate.
2) Battery and charging:
Normal endurance is 1-2 days with active use. If you hardly use the watch, it can last up to 4 days. Active use of features such as GPS, calling or taking photos shortens the battery life. The watch can also be charged while it is on.
If your axle has started to loosen, it's definitely not right, be sure to contact support at

We are sorry that the watch did not meet your expectations. Your feedback is very valuable to us and helps us improve our products!
Thank you and have a nice day, Ondřej - Alza expert
