Review: Holds warm/cold for hours. - Very durable and holds warm for hours. Lid functions good.
Review: Good - Good bottle. No problem with leaking. A bit pricey. When using for a while, water starts to taste like plastic which I think from the straw. Might be an easy fix by hand washing straw parts (we put in the washing machine). See no problem putting bottle and lid in the dishwasher after almost a year of use.
