Was so excited for these just for them to continuously leak no matter what.

Great buy, quick shipping!

Very nice Keep your water cold and fits on the side of the backpacks.

Love that these can be cleaned in the dishwasher. Makes life easier.

Love them

Bought these on the chance they would be a good Back to School alternative to Owala - they are anything but. Believe the poor reviews posted here regarding the straw not working and leaking from the lid. I had the same problem others experienced with getting the straw to work (should be fairly straightforward right?) until I figured out the fatal design flaw. You have to push the flip straw past the point of opening for it to work and keep it pushed - otherwise, no amount of suction will allow the straw to work. Unless you wrench the lid down with an excessive amount of force, expect leaks - but even then it won't matter because the bottle doesn't hold the temperature as claimed. Returned to Sam's for refund.

Sip part doesn't stay open all the way and pinches off the opening to the straw, making it really difficult to drink unless you hold it open by pressing on the tab to keep it open. The chug part is very small and not comfortable. The plastic lid feels cheap.

They are great

Straws are terrible.

Great for my grandkids
