Pros: the dual straw sip/opening gulp feature. Cons: insulation feature: bottle needs to be ALL full of ice before adding water to stay cold for the 24 hours advertised. I've had other water bottles that didn't need so much ice/didn't melt over a few hours.

I’ve had my 6 yr old and 11 yr old using this bottle for a few days now. No complaints, they can close and open it on their own, refill it without any problems and so far no leaks or spills. This bottle will be used for school so we will see how it stands up in the wild. I was able to personalize as well.

I bought these not realizing they have a straw on the inside, but i ended up loving that. You can drink it through the straw or like a traditional bottle....keeps drinks super cold all day long...only thingnis i wish they had a bumper in the bottom of the bottle, but not a deal breaker

I purchased them on sale, which was nice. However, I tried buying silicon boots and paracord handles and neither product works with these. Due to the diameter, no boots will fit. And the way they're designed at the top, there's no room for those paracord handles without the top leaking water. I mean, the bottles themselves are fine. They hold water, keep it cold, have a nice double protection on the spout to prevent 'accidental' opening during transit. However, there are no handles and you can't add anything to work. I'd give 3.5 stars.

I love the built in straw and that this bottle does not have condensation on the outside when filled with ice. I also bought extras for my kids to take to school and they have been perfect for not getting the stuff in their backpacks wet. They have not leaked and I like that the cap locks to avoid accidentally opening.

These are well made and keep water cold for a very long time. They do not fit in my drink holders in the car, so I am using them at the house. I really like the built-in straw and that the lid can cover the drink opening when not in use. Love my new favorite water cup.

I purchased the water bottle because they were inexpensive. After I got them home I used one for work. I gave the other one to my son. We both love the water bottles. I ended up ordering a second set of water bottles for my two grandsons. They were so happy to get them. My water stay cold all day. They are very durable. I would recommend this product to anyone.

They really are! You can sip as if from a straw, but the straw is concealed so it wont kink or get narrow from biting it. You can also raise the bottle to drink as you would a plastic bottle (especially helpful when it’s almost gone to get the last bit). The colors are awesome, and the latch is easy to open one handed. And if you can get them on sale, it’s icing on the cake. Definitely, the best water bottle EVER!! And I have to thank my daughter for telling me about them!

These bottles are huge! Plan on the 32oz not quite fitting in your cars cup holder. But I so actually like them being bigger, so I don't have to refill so often. They really can keep drinks cold all day. My ice from the morning is still clinking around in there by evening if I've stayed indoors. My favorite feature is either the ability to drink from a straw or chug, OR the way the lid completely covers and protects the straw (Sanitary! Yay!) with a locking feature to prevent the lid popping open in a bag. Its perfect for travel. I recommend the 24oz if you're wanting it to fot in the cupholder or fot a little slimmer in your bag. I got the hot pink and bright purple pair. They are seriously vibrant. I love it!

My 4th grader loves this bottle! He loves the invented option of choosing to sip from straw or gulp the drink down. He finds it to be so cool to pop the cover open with the press of a button, then closing the cap to lock it shut with built in handle to carry around is awesome!!
