Amazing, but gigantic. Gave to my partner.
Color: Summer Sweetness, Size: 40 Ounces
5 stars because I got this bottle on sale for the same price as the 30oz, the colors are *gorgeous* and every bit as vibrant as the image shows (which I'm seeing is not typical across the board for owala) and it is indeed just a fabulous, strong water bottle. Easy to drink from the built-in straw, a joy to carry, and fits in every cup holder so far. I've already adapted better hydrating habits compared to using my old daily Nalgene.
However, I am 5'5 and wanted a bottle to carry around frequently for work. This thing is like as big as my thigh bone lol! I should have gone to a local Target or Academy to compare the 30oz vs the 40oz bottle because the size difference is significant. If you consider the added weight for a full 40oz, I set myself up for failure in terms of my needs for this bottle. My 6'2" boyfriend who loves colors and works outside all day was happy to adopt this one for me however, and I ended up purchasing a 30oz elsewhere in equally fun colors. We have both had success having ice last a full workday. His keeps cold in the car and mine usually has a good bit of ice still after 3 refills and constant use. So far so good on no-spills, and I really appreciate the lock mechanism as I work around delicate artwork all day. It would be nice if the cups were machine washable alongside the gaskets, lid, and straw-- but alas, it's easy enough to clean in the sink and probably wouldn't fit in a top rack anyway. Each bottle comes wrapped with beautifully thorough care and use instructions as well-- take the time to read it all!
Overall, I would recommend this cup 10/10. Cold water all day and a built in straw have changed my daily water intake by and large-- so if you're looking to better your hydration habits, look no further and don't overstep your needs like I did if you work around available water spouts all day... The 30oz is enough.
