Nice color and size

I really like however I forget to close and end up spilling them all the time my fault not the cups lol I could no longer lift my 40 oz cups so I gave these a chance and glad I did.

Better than a .......

These are amazing for the price. I've always been a Yeti user and these were recommended to us by friends. They keep water cold for over 24 hours, and the retractable straw and handle make them very convenient

Love them

I love these cups. I use them for the gym. I love that the straws are completely covered when on the go and they DON'T leak! One of the primary reasons I love them so much is the leak proof aspect. They are a little bit of a pain to clean so I don't recemmend putting anything other than water in them if you don't want problems with mold.

Best Design !!!

I wanted to gift a person in an assisted living home with an available water source. This one was great with the handle (4 fingers fit!), the easy to expose and retract the straw for arthritic hands, the travel design for the cup holder (so it doesn't roll around the car) and the ability to keep the water cold.

Easy to carry!

I found my ELLO cups after breaking my tooth on the brand I use to use, these have a soft adult sippy cup top that will not hit your teeth! I love the color combinations and stylish design. I drink water all day a good tumbler is a must, these have a top handle which makes it so much easier to carry than others. I recently gave mine stickers which is a fun way to express yourself. I will not be spending my money on any other brand from here on😁

Ello is always good

Ello products are always great quality. I like getting my Ello products at Same when available due to the pricing.

Not for hot or carbonated beverages

Love the design, however the store description doesn't align with the packaging. Store description says this cup is for hot and cold beverages and the packaging says “Not for use with hot or carbonated beverages.” I give it 2 stars since I purchased it with my morning coffee in mind and am disappointed.

Doesn't work as expected.

I wanted to like these, but it's just not happening. In order for the straw to retract, the cup has to have little ice (not even close to the fill line) and the ice has to be separated. Otherwise, the straw gets blocked by the ice. At least that's what I think is happening. Whatever it is, I don't like it.
