Affordable, sanitary option

Excellent option to get me through a long work shift. The 32oz is a little too big to sit in my cup holder, but it’s well worth it for the volume it holds and how cold it keeps my water. I need to fill it up once or twice during my shift, but it’s a suitable size and isn’t too heavy to carry around the office. I love the straw lid, as it’s fully covered when not in use and is somewhat wider than most straws, making it easier to drink from. The lid even locks in place with the slide mechanism on the side of the lid.It says it’s top rack dishwasher safe, but I just put the lid and straw in and hand wash to bottle, since the sage color is beautiful and I don’t want to risk it, though I’ve seen no scratches after nearly a month of use.

Perfect kids water bottle

This 18oz kids stainless steel water bottle is fantastic! The pastel colours are absolutely beautiful, and my child loves picking which one to take each day. It’s very easy to clean, and the design is sturdy with no leaks at all — even when tossed into a backpack. The insulation works great and keeps the water cold for hours. Overall, excellent quality and a great buy for kids!

These bottles are outstanding!

These bottles are outstanding. They keep water cold for long periods, and the capacity is perfect. I bring plenty of water to work and still have enough throughout the day. I also love the sleek design, and they’re very easy to clean.I reached out to customer service because I wanted a different lid for my daughter, and the specific lid wasn’t listed. Their team was incredibly helpful and kindly sent me a chug lid for free. That level of service truly impressed me.I’m extremely happy with my purchase. I’ve already bought six bottles, one for each member of my family, and we all love them. Highly recommend!

Sleek Design, Leak-Proof Lid, Excellent Cold Retention, with a Few Durability Caveats

I recently purchased the 22oz Ello Cooper bottle in Lilac to use for carrying water with me to campus, and I've been genuinely impressed with its performance and design.Great Lid Security! (A Major Pro) -The lid is the key reason I chose this bottle. There is absolutely zero leakage when the cap is closed. I especially love the security features:Fully Covered Spout: The cap completely covers the drinking spout, which is fantastic for keeping the surface clean when the bottle is in a gym bag or sitting on a desk.Easy Locking Mechanism: The lock is effortless and fast to use (it's super easy to engage and disengage), ensuring the cap remains locked and guarantees leak-proof security when tossed into a bag with electronics.Portability and Size Recommendation -The 22-ounce size is portable and fits easily into my backpack's side pocket. I chose this smaller size specifically because I was concerned that the larger-capacity bottles would not fit in my car cup holder. While the 22oz fits perfectly, with some room to spare even (in a 2026 Corolla), I've found I need more water capacity throughout the day. For my next purchase, I would definitely order the larger size and would recommend others check the dimensions against their own cup holders.Design and Durability Considerations -I have a few points about the construction that potential buyers should be aware of:Cap Alignment Issue: The screw mechanism inside the lid, which is crucial for preventing leaks, can be tricky. It sometimes takes a few tries to line up evenly and screw on properly. It's a minor frustration, but worth noting for daily use.Exterior Scuffing: While I love the sleek look, I was disappointed that the exterior finish already shows small scuff marks after less than a week of daily use. It seems the painted finish may be prone to minor wear and tear quickly.Cold Performance, Cleaning, and Drinking Experience -This bottle excels at keeping drinks cold all day. The water is still cold well into the evening.Cleaning is Very Convenient: The lid is easy to fully disassemble for deep cleaning, and both the bottle and lid can be safely put into the dishwasher, which saves significant time.A Note on the Drinking Experience: The silicone spout is comfortable, but the drinking experience is a personal preference point. It requires slightly more suction, and the rate of water flow is a little less than I am used to (in comparison to my Owala bottle, for example).Important buyer awareness- this bottle is for cold use only!!Please be aware that this specific bottle is not designed for use with hot liquids, which was disappointing to discover after my purchase.Overall Recommendation:The Ello Cooper is a fantastic choice if your priority is a securely leak-proof, fully covered spout design with excellent cold-temperature retention. I recommend it highly, and based on my experience, I'd suggest considering the larger size if you need more volume, even if you were initially hesitant about fit.

Durable, beautiful, and great locking system

These cups are beautiful and sleek and hold the perfect amount of water for my toddlers. My 3 year old can easily open the lid without struggle and figured out the locking mechanism right away. They aren’t too heavy even when completely full. My 1 year old has no issue lifting and drinking from his cup. We don’t use ice so I can’t speak to the insulation, but we love that it’s stainless steel for the kiddos so it helps prevent bacteria and at a minimum keeps their water cool on a hot day. So far we haven’t had any issues with water leaking and the cups appear to be very durable.
