Fitbit Flex is the company’s newly released fitness tracker which is one of their budget models. The gadget has almost all of the things you could be looking for in a wearable fitness tracker, such as tracking sleep quality, steps taken, or stairs climbed. It also syncs data seamlessly with Macs and PCs. The Flex is comfortable to wear, and it is both Android and iPhone compatible. And to top these all off, it is entirely waterproof. Now let’s take a closer look at this gadget and find out its true mettle.

My Verdict: With a minimalist design, the Fitbit Flex features a wide array of functionality that is going to satisfy all of your training and tracking needs. It has a solid uni-body waterproof construction with a battery that will easily last you for 10 days straight. The obvious downside here is the lack of any display which can potentially show you valuable information. To counter that, Fitbit have implemented seamless wireless connectivity that can pair your phone or computer to the band and in turn show you all the information there.

Overview & Features

At first glance, you’d see that the Fitbit Flex is pretty straightforward, unadorned and utilitarian. The display is a thin cut from its smoky dark plastic. If you turn it over, you’ll see a row of 5 minuscule LEDs that blink to present the gadget’s status

The band is made of rubber, but don’t be fooled by its simplicity. The underbelly of the Flex is where all the action is at—that smooth plastic pebble has the tech. The Flex is actually half the size of the Zip and the Fitbit One, making it the company’s smallest personal fitness tracker to date.

You will also find a line of metallic contacts, which are used for charging the battery via the USB cable and socket that comes with the package. Other than that, there are no other frills found on the Flex.

Performance

In terms of performance, Fitbit Flex has an internal accelerometer that tracks steps taken, sleep quality, stairs climbed and calories burned. Flex calculates your activities by factoring in your age, weight and height; data that you punch into your online Fitbit account.

To track your sleep quality, it measures the length of your sleep against the number of times you woke up during the night. You don’t have to wear a separate armband for sleep tracking, like you do using the One. The data presented to you is accurate, and while not as detailed as the data you get from other brands, Fitbit Flex offers useable data that can help you properly assess your fitness status.

Battery Life

The battery life here is decent, even though Fitbit recommends charging it often in order to keep the tracking capabilities to their maximum.

Charging the device takes between 1 and 2 hours and it can last up to 10 days on a full charge, although that might vary depending on your usage. The lack of display surely helps with the battery life but there are competitors out there can easily put out 10 days while having a display.

Design & Construction

flex

The whole body of this Fitbit model is one solid piece. The coating is rubberized which helps when you are sweaty and don’t want the wrist band to rub against your hand too much. It also adds to the soft premium feel of the device.

Even though it features a unibody construction, it doesn’t fare quite well in the waterproof department. Let’s take a look at that now…

Water Resistance

The Flex is water resistant, not waterproof. There is an important difference to that, since water resistant devices won’t be able to handle deep waters. In fact, the Flex is only capable of handling water pressure of up to 1 ATM, or at least that is the maximum at which it was tested. Sweat, rain, and water splashes are no issues here, though, so feel free to take it for a light swim (no diving) and/or a jog.

Additional Features We Liked

Some of the other features worth noting are the fact that it can connect to devices in a 20ft range via its Bluetooth 4.0 system.

It also comes in 5 cool colors which add to the more personal approach of Fitbit and their products.

flexIf you are looking for a straightforward personal fitness tracker that does its job without the frills, Fitbit Flex may be an excellent option. It has all the tracking parameters one usually looks for, such as stair tracking, steps taken, and sleep quality. Its simplistic aesthetics is not a deterrent and it is comfortable to wear.
