Very happy with it. I like how it keeps the drink cold or hot for a long time.

Every time I pour coffee out of this thing it drips. It's a large drip that runs down the side and forms a ring on what ever surface it is sitting on.

I have had this bottle for a few weeks and it is perfect. Very durable, keeps drinks cold or warm. Only complaint is that the opening is slightly too big to sip from.

I bought this to replace a limited edition Canada 150 S'well bottle that was getting pretty banged up from my travels. It was such a great (+sentimental) bottle so I didn't have the heart to damage it more. This one was the perfect replacement, mostly because I don't really care if it gets scratched and dented, so it's a great standard bottle that does its job quite well. I thought I was crazy for thinking that the S'well bottle kept my drinks slightly better insulated, but I recently learned that S'well bottles are triple-walled and Hydro Flask bottles are double-walled, so that could be why. But honestly, the difference is so marginal. I love this bottle for the exact purpose it serves for me.
Finally a bottle that keeps my water cold! I do have to agree that the coating does scratch very easily but it has held up pretty well after a summer of landscaping.
I got the bright pink one, really pops so you can’t lose it around the house ! Great fit in backpack side pockets. Keeps drinks very cold, all day. Highly recommend. One person mentions scratches easily. So put it in an old sock ! Protects it well.
I do love this water bottle, it does keep water cold but as for a durable coating, I don't think so. The slightest knock of the bottle and the coating chips off, after a month my bottle looks very warn.
I bought the Hydroflask on the advice of my daughter. Brought it to Mexico and was pleasantly surprised that my water stayed cold all afternoon in the hot sun. Amazing!
I bought this bottle about a month ago now and love it! I've used it primarily for water/cold drinks and have left the bottle in my car in the sun and my water is still cold. I've also made tea at 6:30am and still had it be warm enough to drink enjoyably at 11:30am. The carrying strap on the lid is great when you're carrying tons of stuff in your hands. This size also fits perfectly in most backpack water bottle pockets and car drink holders. The only downside, is getting used to the size of the opening. It is a bit wider than what I'm used to so I have definitely spilled on myself when first using it. Also the Lilac colour is definitely more of a dusty pink than a pinky purple. Had I seen the colour first hand, I would have gone with the watermelon which was my ... MoreI bought this bottle about a month ago now and love it!
