Question: Are the openings to the bottles wide-mouthed enough to add ice from the fridge dispenser?
Document: I know this is a new bottle for Contigo. I purchased mine in a 2-pack at Costco as well. I can't say enough good about these. In fact I am going through all my other bottles and throwing them out I am so impressed with these.
We live in a hot climate so need to add ice to the bottle - but with this it stays cold all day. Good buy.
These are amazing, they DO maintain water cold for up to 18hours. I left my bottle in the car one hot summer day where the outside temp was 90 for about 2hours and when I came back water was a cold as it was just taken out of fridge and the ice was intact.. I recommended this product with my eyes closed...
Bought these at Costco and was excited about the 18 hours cold....well that is a lie! I have even placed ice cubes in the container and left in the fridge overnight. When I removed the bottle from the fridge the outside of the bottle is cold but quickly warms up as does the water within 30 minutes you do not have cold water. Very disappointed in this product and I WILL be contacting the company.
This is by far the best. I gave all my old ones to Goodwill. (Including several by Contigo) No leaks and it keeps things cold (With ice cubes) forever. Shockingly good! It says not to add hot liquid, but its been fine as long as you push the button away from your face first to let it 'burp'. Very rugged and will take a good amount of banging around without a scratch. I got mine for around $29. Look around to find that price.
These water bottles really do keep ice from melting all day/night and don't leak at all! Just wish they weren't made in China.
I personally purchased 2 sets of these water bottles and i have to say im not sure about the other poster but either its a fake review or they got a bad bottle. I so far have managed to get close to 24 hours of cold when i put ice water in mine. And it was not refrigerated at all. However if you put hot liquids in it at all it will break the cold seal and it will no longer do its job correctly. It is NOT meant for any HOT liquids.
I was really skeptical about the 18-hour claim, so after I bought them I filled one with ice and water and left it overnight. I came back the next afternoon and there was still ice in it! Granted it was in my house so it wasn't super hot but that's still impressive! I can leave it in the car in AZ while I&#34;m running errands and the water stays cold (not saying 18 hours or anything close in the hot car). Love these water bottles!
they INSULATE your cold drinkseven with the insulation, they still hold 20 oz, which is just enough to get bythey are the right size, shape and feelthe spout really does not dripthey even come with a little brush to clean the spout properly and instructions how to best do thatNow, hopefully we won't lose them!
I purchased at Costco and haven't seen them back so found them on Amazon to send to friends. These are truly remarkable at keeping water cold and the exterior does not sweat and make a mess like so many other water bottles do. They are quite durable, I've dropped mine a few times and there are a few &#34;dings&#34; in the bottle, but nothing that compromises the components.
Answer: yes
