don't tumble the tumbler. starts out nice but the lid leaves a lot to be desired. the seal is very hard to clean, the large opening is nice but allows your drink to splash out and with no way to close it, if it falls over is going to spill. I do not recommend this to be used on the go, might be ok if just sitting at home our work.

Really love the actual bottle Really love the actual bottle! However, I bought one as a gift and signed up for "pick up" and it actually shipped to my billing address. So the person being gifted it totally saw it. :( Additionally it was ingraved incorrectly. Nothing that can't be covered up by a sticker, but still mildly annoying. The actual bottle is AWESOME. Would recommend!

Lid doesn't seal completely The product is genius if only the lid screwed on all the way so my coffee doesn't spill all over me between the bottle and the lid. I tried to tighten the lid more but it still gives me the same problem.

Awesome This growler is a great container for a variety of drinks. So far I've used it for craft beer, coffee, and water. It did a good job keeping the beer cold and carbonated, the coffee stayed hot longer than I expected it to, and the water stays cold overnight as long as there isn't too much air in the growler. I particularly like that the top comes off and can be used as a small cup. The only suggestion I would make for an improvement would be to add a hearty D ring to the main body of the bottle so that I could attach a carry strap or carabiner.

Great product. Best I've had in years Honestly I had my initial doubts about this product. I've had other canisters that claimed to keep my drinks cold longer and my hot drinks, warmer. After a recommendation through a friend, I purchased one and am happy with the purchase. My water stays cold and I have yet to try any hot beverages, but I know that it will perform well. My only minor gripe is my dog knocked over the canister from a small desk onto my rug and it left a noticeable dent. I figured this grade of aluminum ( I assume is the material?) would hold up better. Nothing major. Just more of an eye sore. Overall, very pleased and happy. Thanks
