I have been Gathering a lot of water bottles to the point that I consider myself almost a pro. I have found a couple recently that I really liked and this one is right up there with being one of the best. It is well made and feels good in your hand. I like that there's little motivational artwork on it along with time to let you know when to have everything drink by and refilled so that you can complete your goals. It is marked up to 24 oz and it says it holds 28 Oz if you filled it all the way through the lid. There is a part on the top that you can hold on to so you can carry it easily with just a finger or two and the lid is held down with a button release. The straw coming out of the water bottle is a flexible silicone and it's not just the straw shape it's more shaped like your mouth so your lips fit around it easily it is about the size of a quarter. I would purchase this again for the reason stated. For those of those wondering it is marked bpa-free.
