These are, by far, my favorite cups I have ever owned. And trust me, I'm kind of a cup junkie, so I've owned a ton. I'm a nurse, and this holds enough that I'm not constantly trying to fill my water in the middle of my shift. No joke, I started the trend for these cups last winter, and every single nurse on my night shift got one. They're amazing. Don't pass these up! A little more expensive than last year, but still 100% worth it.

Love this cup!

I 100% loved these. Super convenient, perfect size, and can handle cold and hot drinks! I had it for over a year and used them daily! This was up until I started noticing the lids getting loose and one of the rubber straw ends tore. My assumption is that the hot drinks might be too hot and started causing the rim of the cap to shrink. I figured I've learned my lesson: let drinks cool down before pouring them in, so I don't carry boiling hot drinks in my cup. However, I've looked for replacement parts and contacted Hydraflow directly, I have gotten no response about only ordering the parts I need. I don't want to get rid of my favorite cups just because of a small part that needs replacing! That defeats the purpose of having a reusable cup to help reduce waste in the planet, if I have to throw out my entire nearly indestructible cup every time the lid stops working. I wish Hydraflow would be more flexible and responsive.

I love these so much. I look for them often online to buy as gifts. Please restock! These are the best cups ever made.

These cups are amazing! Love that they hold 40 oz and have the built in handle makes them so easy to drink from in the car. Highly recommend. Please bring some back- need more colors!

Worked outside in the hot sun and it kept my drink cold the entire time. Love that it holds a large amount, is not heavy and is easy to pick up with the handle. As a plus it fits in the car drink holder. Plan on getting more to give as gifts.

Worth the money

Love it

Just what I expected

Obsessed with these!
