In the box and first impressions
The Fitbit One arrived in a clear plastic package with many details on the functions shown on the colorful paper covering. I didn't realize how small the One was by looking online and was surprised by how much smaller it was than the Ultra. I also thought the clip was part of the One and didn't know it was just a simple small piece with a clip accessory. Inside the box you will find the following:
- The One tracker
- Silicone and metal clip
- Wireless USB dongle
- Charging cord
- Sleep wrist band
- Free Fitbit.com membership: includes ability to log and track activity, food, sleep, water, body mass, weight, and more.
I purchased the burgundy one since I wanted something a bit more visible than black in case I dropped it or misplaced it and needed to find the Fitbit. Burgundy is sharp looking and I am happy with this choice. I am a bit worried by the silicone clip accessory since it seems the One could fall out, but then again it is very light so it might be just fine. The sleep wrist band is much improved over the one provided with the Ultra and I find it very comfortable to wear at night. I was a bit confused by the charging cord and wireless USB dongle as I will discuss below in the hardware and setup section.
There are a few key specifications that may be of interest to you, including:
- Bluetooth 4.0 to sync to computer and iOS device. (Bluetooth 4.0 dongle included for computers without BT 4.0 support.)
- Rain, splash, and sweat-proof design. Not waterproof so don't take in the pool.
- Integrated rechargeable battery for 5 to 7 days of usage
- Vibration motor that powers the alarm
- MEMS 3-axis accelerometer and altimeter
- Dimensions of 48 x 19.3 x9.65 mm and 8 grams
I found the battery life to match what they list and have charged my Fitbit One up three times over the past couple of weeks. The Bluetooth 4.0 and vibration motor are two key specs for me that have me carrying the Fitbit One daily.
