I put them in the dishwasher prior to use with no issues. Does keep water cold. However, ice does melt faster as you have less liquid in canister. The frustrating thing is the straw keeps coming loose or off, making that drinking option useless. They're definelty lower quality than prior 32oz hydro I bought from Sams.

These seem like a great deal. The price is good and you get a bottle that has a guzzle and straw lid combined. Add to that you get two of these bottles...but it isn't worth it at all. The bottles don't seal at the lid properly no matter how hard you try. So when you use the guzzle lid it will leak. The bottle also makes a high pitched noise when you use it that annoys everybody around you. I am going to be returning these bottles and getting a good brand that I actually have heard of before. It is really sad since the bottles seem cool, have great colors, and nice features. Too bad the basic function of them isn't even accomplished.

Got this for my 6 years old for his summer camp thinking it has more capacity than the kids 14 oz bottle. Unfortunately, the handles are fragile. We broke both within 3 months. When the handle broke, it broke the plastic lid where it is attached to so the entire bottle becomes useless! Very disappointed!

I bought these for my kids and have been very happy with them. It has a dual spout either with a straw or a cap this way it doesn't spill all over. When I put Ice water the Ice usually last for over 24 HRS. Very durable and easy to clean. I have other Hydraflow bottles and they've all been great never had any issues. If you consume a lot of water or need these on the go for your kids I highly recommend these.

I work the whole day outside in a hot weather as a PT and this bottle keeps my drink cold for a long time. It’s the perfect size, it has a handle that makes it very easy to take with me. The color is as pictured and looks modern. It is sturdy too, I dropped it multiple time by accident and glad it is still intact!

These 25oz bottles have been really great for me. The size of the bottle is very convenient as it fits in most of my backpacks since they're not as thick as regular steel bottles. They have kept my drinks cold without spilling which is exactly what I want. The only note for irritation is that when you drink from the twist cap portion (this bottle has dual twist cap and flip straw) an audible squeak can be heard sometimes if you start chugging your drink. This hasn't bothered me, but it may for some. Very happy with this purchase!

We have no issues at all with these. My 6 yr old loves it. I don't have issues with leaking at all. I do not put them in the dishwasher . I always hand wash out water cups. I read all these reviews and am truly confused. We love them. Keeps the water cold and easy to carry. We love them!

I’m trying to switch out my plastic with stainless steel and glass, and grabbed this to switch out my plastic workout bottles. I like that there’s two options for drinking, and I can pick depending on my workout or mood. It’s doesn’t leak and I’m pretty happy with how durable it seems. It also looks really nice in person.

Ice melts quickly you can feel where the water level is through the walls. I loved this brand but not this set I've purchased 5 of the bigger sets of water bottles that work great. Save yourself the trouble.

DO NOT BUY, THIS BOTTLE SUCKS!!! I bought this bottle for work. The straw part doesn't work and the chug part is small, so it keeps getting blocked by ice cubes and the water barely comes. I ended up just throwing it away.
