Love the one I ordered before and bought a 2nd so I have one available when cleaning. And make sure you clean it! I had no idea some icky stuff was building up under the lid and took apart the whole thing to clean it throughly. Why did I let it get this way? Because I drink Waterdrop every day. I love most of the flavors. With this 30 oz container, I place 3 tablets along with some ACV and a little salt water. YUM! I recently pulled out a powder pack of Strawberry Crush and it was terrible! I couldn't wait to pour it out and get my Waterdrop back in the bottle.

Love these tumblers! They truly do not leak and I love that I can throw it in my bag and not worry. Taking it apart to clean is easy. Better than any other tumbler I've tried.

This is the best product in the Waterdrop line. It is truly leak proof. The fit in my Jeep cup holder is snug. Keeps my drink cold all day.

Fantastic. Wish it had a glass straw that you connected to the mouth piece straw and not plastic

It was good while it lasted, it hasn’t even been a month and a few specks have appeared at the bottom of the bottle. I have only used this bottle with water or infused water from Waterdrop cubes. I have other name brand bottles that I’ve had for years and this hasn’t happened to any of those. As I was taking the photo just noticed peeling on the top of the cup where it’s always protected by the top cover. I am more worried about the marks inside than I am of the outside.
