Pros: Stands out for being a stylish monitor that can be worn 24 hours a day. Is waterproof, and the battery will last longer than a year of continuous wear. We also love that it comes in several fun colors.

Cons: Doesn't offer as many features as the Fitbit. To maximize fitness tracking and monitoring, you have to download a Garmin app.

Summary: While the Mio Alpha is rugged and accurate, it lacks features of other models that are similar in price.

Pros: A straight-forward design that is easy to use and program. Gets high marks for its vivid display and the Indiglo night light for easy viewing. The battery may last for 2 years or longer.

Cons: Lacks the technology capabilities that models like the Fitbit and Garmin offer. The chest strap is a bit awkward to use.

Summary: A no-frills heart rate monitor from a trusted company. We recommend the Timex T5G971 for users who want a basic model that is accurate and durable.
