Having worn a second Fitbit Charge until I broke the 2nd watch band, I found this watch with a spare band for less than the cost of replacing a Fitbit Charge. I have no problems with the Y7 model smartwatch. It does everything as advertised, and at this price I am extremely happy. The battery charge lasts much longer than the Fitbit Charge 2 by days!My only complaint is about the "Da Fit" app for iPhone that allows you to change watch settings. It was obviously written by someone with English as a second language who did not bother to have a native English-speaking person review their App interface. After choosing a 12-hour clock and imperial (misspelled as "Imperoal") measurements, I am surprised that the readouts in the App are still 24-hour measurements! There are 3 watch faces to choose from. Notifications can be set for phone, messages, Facebook, Twitter, WhatsApp, WeChat, Instagram, Skype, KakaoTalk, Line, and "Other." You can set alarms, but only 3 of them, but that is all I need. it acts as a remote shutter release for the iPhone camera, and has a "find device" feature to vibrate the watch when you misplace it. If the watch is out on a counter it is enough. If the watch is under a bed sheet you will not hear it. I would like to suggest an option to sound an audible alarm sound from the watch for this feature, but I did not know this feature was available when I bought it, so it is still a plus! You can set a language, including English, German, French, Spanish, Italian, and Portuguese, along with 7 other languages I cannot read to determine what they are, although one looks like Russian Cyrillic, and another like Arabic, and 3 Asian languages I cannot identify. the reminders to move are based on time alone. If you are walking when the timer occurs, it will tell you to move, even though you already are. (Not a deal-breaker for me.) The weather isn't determined by where you are, but by what location you set, so I can set it to find the weather in another city instead of my current location. I would suggest that this would be more useful if it tapped into location services to determine your current location to get a weather forecast there and not where you used to be.All-in-all I am very happy with the watch. I just have the previous suggestions about the "Da Fit" App by "yi xu" in case he/she/they read this review. It sure beats the price of a Fitbit Charge 2 for this price!It is March 12. 2020, and it still works fine. I have only used the black band briefly, then switched to the blue band after two weeks to try a different color. My favorite feature is that I can set an alarm before the end of the work day that just vibrates the watch so that I can silently prepare to leave work without disturbing co-workers. I can tell when thre iPhone rings, even if the iPhone is set to mute, or I am in noisy environments. I would recommended this watch to my friends, and I have!
