Garmin Vivofit 2 Review
First of all, it needs to be said that you have a useful option if you decide to purchase this product. You can choose whether you want your Garmin Vivofit 2 to measure your heart rate or not. Including the heart rate monitor will cost you $30 extra, but it's a useful option for people who really need it. The display never turns off and it stays active and visible in all conditions with its backlight for night and considering the fact that it's completely waterproof. Also, the battery life is great and the manufacturers claim that it last more than one year before replacing.
Pros / What Customers Like:
You don’t have to worry about recharging it every once in a while since it’s always on, for up to a year.
The fact that it’s waterproof makes it a great choice for swimmers, scuba divers, etc.
It offers a function where it reminds you to stay active every once in a while and it’s deactivated by standing up and walking.
The screen is always bright and on, and the backlight can be turned on in the dark.
Cons / What Customers Don't Like:
Most customers have complained about its audio-only alerts which can become annoying and almost everyone would prefer vibrations.
There is no option for setting your own alarms and alerts.
Overall, this fitness tracker is a very nice purchase and it should be satisfying to a large crowd. It offers some serious improvement over the previous model, and options such as backlight and audible alerts have been introduced. It also utilizes a sleep mode where it can track your activity during sleep. If you forget to turn it on, you can use the app to set just how much you slept. The design is simple and the band won’t bother you, and neither should the price tag.
