I have gone through many, many travel coffee mugs that have been listed as top picks on various authoritative blogs and websites. None of which listed my Owala. Here's what makes it perfect (and one suggestion): 1. The sipping mechanism is flawless. No drips, smooth flow, and very easy to clean. 2. It is genuinely a one-hand operation. Yes, the slider can be stiff...but that is a matter of strength and not poor design. Leakproof does require tightness. 3. It fits into cupholders in my car with no jiggle. The slanted sides allow for a snug fit in various cup holder sizes. 4. It keeps my morning coffee hot all morning. Now for the suggestion...some type of handle would be nice but with all the other positives its a small thing that a third party can help with.

This amazing cup absolutely does not leak and keeps my drink hot for hours. Love the cocoa color! Owala is the best and I love the 12 oz size, it’s perfect for my second cup I take on the go.

I love this mug! I waited for it to be on sale and when the price dipped I snapped one up. 12oz is just enough to get my coffee fix without over doing it. This Owala Mug is easy to clean AND put back together which I appreciate it. It truly is leakproof and I have had to test that feature a couple times during my morning school drop offs. As long as you close the opening, the code will stay warm for hours. My one annoyance is that the texture of the exterior makes many of my cheaper stickers and navel to properly stick. I do notice more high end/quality vinyl stickers do just fine. Overall, this mug is the perfect size for my needs and worth checking out!

For the price I wish it kept the beverage hot longer than 4hrs. Using this every day for my tea. It does hold liquids hot for 4hrs... by the 5th hr it's just lukewarm. 😔Miss my old mug that was holding my hot beverges for 8hrs.

This cup is perfect for a small coffee and it is perfect for being on the go. I am often throwing this in my purse and it has never leaked. Such a great versatile cup and keep your drink at the right temperature for hours.

Best coffee cup I’ve ever had and I’ve had a lot. Coffee stays good and hot without compromising the taste. A bit pricey but turned out to be a great buy. Completely leak proof too. This cup is pretty impressive.

I am so happy with my purchase! Very sleek and it comes in several beautiful colors. I bought one to try for coffee and tea and quickly went and purchased two more. High quality and the drinks stay hot for hours! The slider option is great and ensures that there is no spilling. Easy to drink from and easy to clean. Perfect gift for the holidays!

I love this tumbler, it really doesn't leak. BUT.... I give it a 3 stars because unfortunately Owala makes it VERY difficult to use if you lose a part. I lost the gasket. I can't buy it from them, they offer NO replacements parts, don't recommend using a third party part and their suggestions is to buy a new one. They will offer free shipping but I have to pay another $25 and have two mugs. Really? That's a solution? People loose gaskets all the time. Why wouldn't they offer to sell them?

Muy lindo y cumple muy bien sus funciones, y lo mejor sin derrames

AAbsolutely LOVE this cup. I’m a soccer mom and in Canada during winter our kids play in domes and we’re not allowed to bring anything inside other than travel mugs. My Stanley coffee mug is too big, my yeti mug is too small and this 12oz one is just right. Keeps my coffee so hot that when I get there, I can’t even have a sip because so hot till i open it to cool down. I also turned the cup upside down with full hot coffee and when locked not one drop so definitely spill proof. Fits my car cup holder easily. Love the colour I chose and just ordered another one in pink for my daughter for her morning smoothie. Strongly recommend.

This bottle came like that and it’s my first time using it today. I can’t drink from it at all, was wondering if it’s suppose to have some kind of cap to help me lock/ unlock bottle?

What a great cup. And the colour is perfect

Delivery received well but there is a discolored or stain at the cover that cannot be removed..
