Looks excellent. A copy of Nike's expensive hyperfuel bottle. But as it's a copy don't expect it to be ad effective as the original. You should refrain from using the nozzle for drinking water while squeezing it as you can hurt yourself in the mouth. Because you need to apply some tremendous pressure on the bottle to squeeze the water out. So whenever i need to drink from it i end up removing the cap like an ordinary bottle. But there's a positive side to it as there's no leakage even when you tilt it upside down. But that's what you can expect from a copy. If you have money to spare go for the original or if not you've got this option. Looks cool.
