Alas, the first one only lasted 10 months, but I liked it so much I just bought a second one!
I never expected to wear a watch at night, but I love the sleep function, and the readout the next day is usually spot on my own perception of how I slept. I also love being able to check the time if I wake up.
I’m recovering from an injury, so I originally bought it to give me a way to track my steps and rebuild my endurance. The step counter works great!
One function I never thought I’d use is the tiny flashlight, but I use it constantly! It’s great for a little light on the way to the bathroom or to read a thermostat or see a keyhole in the dark.
Another function I love is the countdown timer! It’s great if you use the pomodoro technique (working in increments with breaks in between), or you just want to do a 15 minute cleanup, or you need to remember to leave in an hour. You can also set up to 3 alarms each day, or an hourly reminder to MOVE.
Anyway, for the price of this watch, I’m amazed at how much it does. The battery life is great, although it does decline over time. When mine first one died, I bought another one— pretty much says it all.
