Contigo Shake & Go Tumbler with Leak-Proof Lid, 20oz Water Bottle & Iced Coffee Tumbler with Shatter Resistant Material; Fits Most Cup Holders, Iced Coffee Brewers, & Dishwasher Safe

This really is the perfect cup. It holds a high amount of liquid 20 ounces, it’s see through which I like to be able to see how much liquid is left, it keeps the drink cool for a reasonably long period of time 1-2 hours, if you knock it over it spills a very small amount, it’s easy to hold, the straw is quite easy to clean with a thin brush, extremely well made mine lated around 2-3 years before the straw finally cracked. All in all You really can’t ask for a better cup.

I absolutely love this! I was tired of wiping the condensation off my old iced coffee mug, and so this double-wall tumbler is an amazing change of pace. I walked to work all summer using this tumbler and my iced coffee was still cold, while my hands remained condensation-free.I chose this tumbler because it uses a straw and it seemed easier to take sips while walking, and it has been. I have yet to see how leak-proof it is if you remove the straw, but that's usually because my iced coffee is done by the time I get to work. Then I just rinse the mug and stick it in my bag, and so far it has yet to get scratched or cracked. I did buy extra straws since other users said theirs cracked, but that hasn't happened to mine and I've had it for a couple months now. I personally think it's quite sturdy and I don't see myself replacing the straw anytime soon.As for care, this tumbler is very easy to clean by hand. There are no hidden crevices that a sponge can't reach, and my small-ish hands don't have a problem reaching the very bottom with a sponge. I've only used this for iced coffee and so I haven't had a problem cleaning the straw without a specific tool. I just run warm water and soap through it, and my drinks have continued to taste perfectly fine.The only downside is somewhat a personal problem, hah. The small-ish size of my hands make this tumbler just a bit cumbersome at times due to its diameter, but not enough to make me want a new mug. (Note that my hands are below average size, most adults shouldn't have a problem!) Overall, I love this tumbler and I highly recommend it!

This is currently my favorite on-the-go cup. I have both the 16 oz. and 20 oz, but find that I use the 16 oz. the most. Here are the things I like about:-Having a clear tumbler was a must because I love making layered drinks. Have a look at the uploaded picture: iced strawberry almond milk with matcha latte. Beat that, Starbucks! The trick is to use lots of ice. Also, layer the liquid with the most sugar content on the bottom.-If it is a drink that needs to be mixed, I am able to shake it up without the straw inserted and there are no leaks to be found.-It feels pretty durable and has no scratches. I do use this tumbler quite often.-It's convenient that I can just throw everything in the dishwasher.*UPDATE* 3/20/2018It's been a year since I've purchased these tumblers and still going strong! I haven't found any other product that I would like better. The straws broke recently, but I think it's due to my negligence when handling them. No big deal. I might purchase some stainless steel straws to use.

I purchased and have been using this cup for several weeks. I love it! It is exactly what I was looking for, something that is sturdy, looks good, is easy to hold, easy to clean - all at a great price! (For some reason the clear cup was less expensive than the colored cups - I wanted clear.) The shape is perfect - tapers slightly only in the middle, making it easy to grab and hold, but it does not taper down at the bottom. Many other cups are slimmer at the bottom to fit in car cup holders and feel too top-heavy when using them outside of the car. I use this cup at home, and it looks great - not like I'm using a water bottle. I never worry about this cup tipping over. It's insulated enough to hold my iced drinks for a reasonable amount of time. I After trying many different cups that I bought at different stores, this is the best cup I've tried. I'd buy it again, and I'd recommend it to anyone.

I love this water bottle! I work an office job and try to drink the recommended 60+ ounces of water daily. I have gone through several water bottles. I have found that water bottles with a simple straw are easiest to use and encourage me to drink the most water. I had a cheap straw water bottle for 6 months and it would no longer screw shut due to overuse. So I then purchased this one. I already have a Contigo coffee cup and it has held up very well and is well made. This water bottle is well made, a pretty purple color, and easy to use. I also love that when the straw is removed there is a small piece that snaps shut making this bottle spill proof and also easier to use as a shaker bottle. I trialed Plexus Slim (a powder supplement that is mixed with water). It was very awkward to mix it in my cheap straw water bottle. I wish I had this bottle when using Plexus Slim. If I ever have the need for the shaker feature of this bottle in the future, I am all set! Other water bottles I have tried include Brita, Klean Kanteen, Camelbak Eddy, Nalgene, a cheap infuser water bottle, a cheap straw water bottle. This one is my favorite! I love that this is a larger size (20 ounces) so you can drink more at once. My only gripe is that because it is a taller water bottle you cannot easily fill it up in a shallow sink.
