"This is our 2nd bottle. It’s great for traveling & daily use. Easy to clean (we have a bottle brush & I use a pop cleaner for the nozzle). Very durable. Somehow keeps water cold (enough) even without insulation for walks on a hot day/in a hot car for a limited time."
"The bottle is comfortable to hold, easy to carry, clean and fill. The extra wide straw means you get a lot of liquid with each drink which is great. There is no residual taste like there is in many plastic bottles. 27 oz is smaller than I expected, so I’ll probably order a larger size bottle next time."
"This was a big WIN in our household: me wanting to ditch plastic water bottles, my husband resisted until I showed him this super cool "sippy cup" as we call them. He even loved the bright colors available!! I'd send a picture of the extra bright green lid w/handle, but husband is off to work with it :>)"
"Family members in my home don’t care for the straw part so they were using the lids without the straws. Then liquid started to pour through the little vent hole on the lid into our faces. We prefer the old lids. Please bring back more colors with the old lids."
"I’m a fan of this red. Mama finally has a cup color she loves. The new cap is an upgrade from the sport for sure and as someone who hates change I don’t say that lightly. I choose to use it without the straw, for me that’s the whole reason I use this cup vs a cup with a straw is to avoid the extra clean up step. My only minor complaint about the cap is that without the straw you’ve got to turn your cup sideways to tip it back to drink otherwise the loop is hitting your nose preventing you from tipping further back. Does make it a little inconvenient to awkwardly drink from the sideways spout, but minor enough I’ll still be purchasing more of the new lids to replace our falling apart sports cap components. This cap is much easier to clean, still need a tiny brush to get down in there if it’s really dirty or you aren’t utilizing the dish washer, but serious improvement from having to pull out the sports cap spout to clean the entire lid and have to put it back together on top of the repeated taking apart causing the tip of the spout to come off. We all use a different cup color from age 2 on as a family of 9 (and growing) so I hope to see even more colors and shades be added going forward, especially for the caps to customize our choices to our liking."
"My son is always on the go for his job. This water bottle is lightweight, well designed (no leaks, easily accessible lip,) is customizable and durable. It's worth the price. Go for it!"
"They sell replacement parts and everything. Wonderful product."
"I love Klean Kanteen bottles but I feel like their sip lids are hit or miss. This lid is the best one so far (with the straw)."
"Good size bottle. Holds a lot of water but not too big or heavy to carry. Very secure with no leaks!"
