Quality of Fitbit products has been crap so far. Not only did 3 devices fail on me so far but the software itself has been buggy as well.
I do not recommend Fitbit and I would not buy another of their products.
When I see these horrible mockups, I immediately realize that the whole rumor is as fake as these images.
EVERY time Apple is about to release something, there are these idiotic rumors about delays. Genius of them is that you cannot disprove them.
