Review on Smart watch Apple Watch Series 7 45 mm Aluminum Case, dark night by Cheong Yon ᠌

After watching the reviews, I bought the 7th series . In 2 weeks of operation, the glass was scratched without any incidents, just on clothes (a button) and once on a painted wall in the office. For comparison, I have old Casios that I wore all my childhood and youth and there is nothing like that with their glass. The watch is 41 mm, but very heavy on the hand and constantly felt. Chips in the form of ECG and oxygen measurement need to be specially carried out by yourself and it takes a long time and you need not to move . The device itself does not activate ECG and oxygen measurements in any way and cannot do this in the background. Bicycle training only shows average speed, who needs it? It turns out that it cannot determine the fastest speed and does not replace the bike computer. Conclusion - worthlessness, the worst device from Apple. Don't waste money
