For the price of about 500 CZK, it's a great watch with great endurance, which as a bonus can measure temperature, heart rate, saturation, monitor your sleep, steps, wake you up, find your phone, and has a stopwatch/timer. Most watches under 3k basically can't do much more and the battery lasts less. However, I compared it to the WowME ID205U, which has a slightly smaller display, but has better sensors, more health features, even more battery life, is waterproof and displays a bit more information on the watch. iGET probably have a more robust strap, one spare and the magnets for charging are hidden so they don't rust like WowME. Overall, however, I was not convinced and returned them. Finally, I'd add that I think an ideal watch should also be able to provide an accurate ECG, blood pressure, swimming record and have the ability to share health information with family members in the app. Pictures, calling, NFC, GPS, etc. are just useless, battery-draining things that the phone is used for. Unfortunately, even a 10k watch can't do much more than this cheap one. PS: To turn them on for the first time, they need to be charged to 100%.
