Worth it!
Holds 32oz which is enough for my kids to get through the day at school. It keeps liquids cold all day, their drinks are sometimes still cold when I change them the next day! They're simple in style, which is great for kids with stickers. The three different lid types is also a bonus. Lastly, they're very durable! Im buying my second set because the ones we bought last year made it through the whole year!

SURVIVED SPACE MOUNTAIN
Hands-down, this is one of the best water bottles I’ve ever had! This keeps my water cold for hours. I absolutely love the small chug top. It has the perfect water flow amount and it securely seals so no water leaks in my bag. I had this tied to the side of my backpack in the water bottle pouch, while I was in Disney. I went on Space Mountain and on one of the bumps, it came out of the pocket and slammed against the track. Luckily I had it tethered to the backpack or it would have been a goner. As you can see, it is quite dented, BUT IT STILL WORKS! The material is thick and it didn’t puncture, there’s no leaks. When the rubber bottom is on, you’d have no idea it’s damaged. It cleans extremely well, I only use water in it, but the opening is wide enough for a bottle brush. I love the handle, it’s easy to carry if I don’t have my bag.

WORTH IT
This definitely exceeded my expectations! Keeps my drinks cold for hours, feels super durable, and I love that it comes with multiple lids, straws, and a cleaning brush. The design is sleek too, like a tiny portable glacier 🧊💙 Definitely worth it!” Very easy to carry, color didn’t disappoint!

Just as good as a name brand reusable water bottle
Keeps fluids cold for as long as the way more expensive water bottles. Plus it comes with three types of lids and a removable protective rubber bottom. Only downside is it’s too wide to fit in cup holders. Highly recommend.

Very good but not great
Welcome back, fellow consumers. Let's talk about the RUBYFLASK 32oz Insulated Water Bottle, shall we? It's a pleasant color and the padded base both adds durability and stability. I really appreciate the flexibility this offers with having three lids. Make sure you pay attention to the diameter of the base of the version you choose; even the 32 ounce has a wide base that doesn't fit well into many modern car center consoles. This isn't enough to remove a star, though. I'll tell you what removed a star for me. First, the straw has a hard time reaching the bottom of the container so I always wind up having to unscrew the top and finish off the last two or three ounces that way. If I loosen it a little from the cap then it can reach the bottom of the flask. But then it frequently falls out of the cap and the straw rattles uselessly inside the flask. Also, while it keeps liquids nice and cold if ice is included, it doesn't do as good of a job keeping cold liquids cold without ice (like my old Bubba flask did.)

Works great, has extra lids and straws and doesn’t make noise.
I got a few Insulated water bottles a while back and every one with a straw made so much noise, like I am sucking air as well as water. This one didn’t and it keeps my drink nice and cold.

Great bottle for the price
I've been really happy with this water bottle. It does exactly what it's supposed to do, and I haven't had any complaints with it. , same as evey other bottle easy to drink holds a good amount and a pain to clean. One feature I really liked was the rubber bumper sleeve on the bottom. It helped protect the bottle from little dents and dings and also kept it from making a loud noise every time I set it down. The handle on the lid is also really convenient. I like clipping a carabiner to it when I'm camping or hiking since it makes the bottle super easy to carry or attach to a backpack. There are also a lot of fun color options to choose from, which is a nice bonus. I eventually broke the original straw lid, but I replaced it with a Hydro Flask straw lid, and it fit perfectly. Personally, I don't like the flexible handle on the replacement lid as much as the solid handle that came with this bottle, so I actually prefer the original design. Overall, it's a simple, well-made insulated water bottle that works exactly as advertised. It's durable, portable, and a great value for the price. If you're looking for a solid everyday bottle without spending a fortune, I'd definitely recommend it.
