Cons

Con Unreliable altimeter
The socks sometimes have trouble detecting changes in elevation.

Con Only one sock is active at a time
The socks feed data to a single anklet, and information for both feet can't be gathered at the same time yet. This functionality is planned.

Con Doesn't catch some bad running techniques
Currently the fitness tracker covers a relatively small subset of bad running techniques. It's possible to be in a situation where the technique is bad and the device is not aware of it.
Con Very few customization options currently available
Some of the fitness tracker's customization options are planned, but not yet available.
Con Very unreliable build quality
There are many reports of the track malfunctioning right out of the box or after only a few hours of use. This includes the LED display not working, the heart rate function not working, and buyers being sent used products.
Con Heart rate monitor is very unreliable
Along with frequently not working at all, it has a tendency to be quite inaccurate. It struggles to read the HR when you're sweating as well so isn't useful during exercise.
