I've had this bottle for about 7-8 months now and I am happy with it. It is a good size and I've never experienced any leaks with it.
I take mine to the gym so it gets thrown around in my back-pack quite a bit on my travels to work and then to the gym.
The only downside to this bottle, which might be obvious to some people, is that it is not the easiest to drink from when you are moving! When I'm on the treadmill I have to be extra careful when taking a drink as it does tend to just pour out when tilted as there is no closing mechanism - this is the only reason it loses a star!
The design has in no way faded which is good as it is so nice to look at!
