The $100 Flex 2 is Fitbit's first waterproof tracker (hands-on)


The Fitbit Flex 2 just might be the most stylish Fitbit we have seen to date.

Great product!


My wife bought this for me to keep track of how much I move about. It's easy to connect with my phone and also provides feedback on my sleeping patterns which fascinates me. Not sure how it can track high intensity as I go to the gym regularly to...

Semi-reliable pedometer


Purchased this for my mum, after it went on sale for $40 (???) at the Co-op Store. We've had some problems with synchronising the Fitbit with a Microsoft Lumia 530, meaning that sometimes it can simply become a glorified pedometer that reports progress...

I love how slim and comfortable this tracker is. If you don't want a watch face and want a basic wrist tracker it's a great choice. However, I bought it for the jewellery accessories and the necklace in particular was cheap looking and tangled really...

Upgraded from flex 1 and it's still great!


I purchased this to replace my original flex. No complaints here. It's a basic unit but I like that about it. It's also waterproof which the old one wasnt. It's very easy to set up, use and charge. The app for it is awesome. It shows all your...

What a great motivator


I purchased this Fitbit 2 in 2016, its still going strong and is a fantastic way for an older person to keep track of their walking, sleep food etc. I love the fact that its easy to log onto your computer and that I have a daily record. This is great...

Fitbit Flex 2 - This is an excellent product.


This is my first Fitbit. I wanted a simple device to encourage me to be more active and the Fitbit Flex 2 is doing that. I am not overly tech savvy but it was easy to install on my computer and iPhone. At the beginning I wasn't interested in more than...
