I enjoyed this product, with it's sleek look and simple features. However, there were frequent issues with the pressure and opening. It spat water with every single opening, which was fine when it was only a few droplets, but during one occasion, it continued to erupt water like a volcano right after opening, spilling all over int he car. There was also a lot of water buildup around the screwing of the top, so opening it in any way was almost impossible to stay dry. And though I first appreciated the straw being part of the bend, it does create some extremely difficult to clean bends where a major amount of buildup occurred. Now, less than 5 months later, there is a hole in the straw in the top part of the cap, which is odd to disassemble to say the least. Upon taking it apart showed a small pocket where the buildup collected that would have been impossible to clean.
