I've had this for about two weeks now Using it primarily to drink water nothing else It keeps my water icy cold. Let's be real, nobody should have to test and review how long the ice lasts in the cup with the same amount of water. If I wanted to keep the cup full of water, you'll expect a cup full of ice. But if you're consuming water, refilling it up with more water throughout 8-10 hours in a day, expect your ice to melt. It's the reality and my water stays nice and cold. I haven't dropped it yet to experience any dings or broke mouth piece. I just wish it included an extra straw. I do let the cap air dry overnight to avoid mold building up in the tiny corners underneath the straw that has a rubber / silicone part between the plastic cap and the straw. It's not easy to take apart to clean otherwise I would've given this an easy 5 star rating. given I have a teal I wouldn't recommend boiling the lid either as you may stain the silicone. The best part, it doesn't leak and it's double threaded for ambidextrous people like myself. Pros: Flip straw - I don't have to worry about straw exposure Ambidextrous flip straw Leak proof Cute color Keeps beverage cold over 24 hours Con: Hard to clean the corner that some people have addressed mold build up on tiktok / Facebook (thankfully no mold experience yet just let it air dry over night) Should include a boot to avoid dings Doesn't come with extra straw like most competitive bottles do I'm curious if there's lifetime warranty on these things, as some big companies offer any case of any defects Now I've seen and read people have bad experience not receiving theirs on time. The email disclosed on when items shipped based on inventory and if it's a preorder / sale item Their customer service does take at least 48 hours. So sending more than one inquiry will put you at the bottom of the waiting list.
