Final Update (12/19/24): Hydrapeak was out of the mug I wanted to buy for my juice. I didn't feel like waiting. So, I purchased a $12 cup from the dollar store (more like 5+ dollar store these days). That was a mistake! My juice was watered down by the next morning, and the straw didn't even work that well. I'm returning it and I ordered another Hydrapeak!Update:I reviewed my first Hydrapeak on September 30, 2023. I bought a second one this year (2024). I just wanted to give an update. I still love my Hydrapeak just as much as the day I got my first bottle. It still keeps the water cold. Timing does vary with how hot the outside temperature is. I still get an average of 3 days, even when my AC broke, and it was HOT in my house. I have my bottle sitting on my desk as I write this. I have yet to buy any other water bottle because this one is perfect for me. I don't think any other water bottle would beat my Hydrapeaks. I've only ever questioned whether I should get a third one. Thanks, Hydrapeak! Original Review:______________________________________________________________________________________________I cannot begin to tell you how many water bottles I have gone through… I have a problem with water bottles. I seemed to be on an endless quest for the right one. I can honestly say that, the quest is over now! This water bottle is absolutely perfect!1. It keeps water cold. I have seen ice in the bottle 3 days later! No, idea how.2. It's a nice size. I have the 32oz one.3. It has a nice little handle to carry it by.4. It seems to be pretty sturdy. It fell off my desk a few times and it's fine. It has a minor dent that is hardly noticeable.Things to know: If you have small hands like I do, you may want to get a little carrier with a handle on the side. I just used one from a previous water bottle. The little rubber seal on the inside may come out. It did for me when I first got it. It hasn't lately. One time, I was confused when I felt some water fall on me. Only to find the little seal in the bottle, lol. So, just be careful when you're washing it. I have noticed that some people claim that it doesn't keep the water cold. My friend recommended this water bottle to me. I know it works for her. I'll just tell you what we do, and it works for us. We fill the water bottle to the top with ice and then, add cold water. Like I said, it keeps the ice for three days for me. Obviously, some ice melts, but some is still in there. I have never taken a sip of water from this thing that wasn't cold. I've had this since last year. I loved this water bottle so much that I ordered another one! It really is the perfect water bottle!
