A fitness tracker at an amazing price

Fitness trackers are getting big-time smart, not just logging steps, but also hours you sleep, quality of hours and stairs you climb.

Your watch knows all about you.

And at costs running north of $300, it should.

But there are some more inexpensive offerings around, among them the $25 Wyze Band. It counts steps, monitors heart rates, supports Amazon Alexa commands, and you can swim with it on. Best of all, its battery is good for 14 days. This is almost double the battery life of other, more expensive smart fitness trackers.

A similar tracker, Fitbit's Inspire 2, does the same thing, but includes sleep tools. Battery life is 10 days. It costs $99.

Ironically, like all the fitness trackers in this category, user reviews complain the displays can't be seen outside. So, when outside, you never know the time or how far you have run.
