Pros
Pro Social component to help keep you motivated

Pro Easy to hide under your clothes
The Fitbit Zip fitness tracker is very small, so you can easily wear it somewhere that it will be hidden (belt, pocket, bra strap, etc.). Unlike most trackers which have wrist bands, you don't have to worry about trying to make it blend in with what you're wearing.
Pro Fitbit app lets you track a variety of health-related stats
The app doesn't only display the stats from your device, it also lets you track a variety of different health-related stats by entering them manually. You can log your food for the day, how you slept, activity, weight, and more.
Pro Automatic synching that's easy to setup
The Fitbit Zip fitness tracker wirelessly syncs with both PC and smartphones via the Fitbit app. After getting it set up you don't even think about syncing, it's just automatic.
Pro Great option for swimmers
The fitness tracker is completely waterproof and keeps track of your laps, pace, and total duration of your swim.
Pro Sleek design fits a variety of occasions
The Flex 2 is a thin band all the way around that has a modern and sleek design. Since it isn't super sporty in appearance, you can confidently wear it for a lot of different occasions without it looking out of place.
Pro The app and web platform do an excellent job of keeping you motivated
The Fitbit app lets you set goals and milestones which reward you with badges and trophies when reached.
You can also challenge friends and family, competing against them for top spot on the leader board.
Pro Replaceable wristband with lots of options available
The fitness tracker itself is a separate part from the wristband that can be taken out and put in a different band. Therefore, not only are there 10 wristband colors to choose from on the official store, a different color of band can be worn every day with the same tracker. There are even custom bands available from third-party vendors.
Cons
Con Lacking many of the features that fitness trackers often offer
The Fitbit Zip only tracks distance, steps, and calories burned. It's basically a pedometer with a smart tracking platform you can use for manually tracking the rest of your day. It can't tell you stairs climbed or heart rate, and there is no alarm, sleep tracking, or GPS.
Con Issues with the battery not working
The contacts in the device are very sensitive. If you don't place the battery in just right, it will only work for a short period of time before the battery needs to be readjusted or replaced.
Even when following instructions provided by the company, some people report that still can't get it working properly. The battery may end up lasting days instead of the promised 4-6 months.

Con Easy to lose
The tiny size of the Fitbit Zip makes it very easy to lose track of.
Rather than a wrist watch like many other trackers, it only has a slide on clip. The clip is fairly secure for normal activity, but you may knock the tracker off without realizing it.
Con Lacks a rechargeable battery
The Fitbit Zip fitness tracker runs on a 3-volt lithium-ion battery that lasts between 4 and 6 months. It requires getting a new battery every time it runs out of charge.
Con Underwhelming battery life
The fitness tracker's battery lasts about 3-4 days on average.
Con Can't be paired with external HR monitors
The Fitbit Flex 2 fitness tracker has no built in heart rate monitor and lacks the ability to pair with external HR monitors.
