I had a Nike Fuel band first and adored it. Multiple issues! The first one out of the box didn't work, second one worked 4 months and last one made it 7 months. I purchased a Fitbit about 6 months ago.
Pros: it's on my arm and I can tap it to see if I have met my goal of steps for the day by little lights that light up as I progress thru the day.
Cons: It has lights only. My fuel band showed exactly how many steps & calories.
It has a rubber band feel and is stiff so I can't stand to wear it at night.
The fuel band was more like a bangle bracelet.
The bands can break easy and it's hard to get on.
You have to clean the little hole the tracker goes in.
You have to charge it every 4 or 5 days and it takes forever to charge.
It you don't have a smart phone and don't check your email often then you have a dead Fitbit.
Fuel band went 7-10 days charge and you could see it needed charging.
I wish I'd done more research and picked something different.
