The step counter of this device is accurate at some point. When I move my hand it record this movement as step. If you walk differently or wave your arms around a lot, you’ll get different results. That’s an issue that all fitness trackers have. The battery life of this device is very good. But it wasn’t all that comfortable or flexible to wear. They do come in a couple of sizes, so if you can try one of before you buy. There’s no touchscreen, but these aren’t always the most responsive on these affordable bands. The sleep monitor is also not so much accurate.
