Bests & Worsts Reviews from Amazon

Love this bottle. Flow rate from autoseal is nice and fast. Seals nicely. Keeps my cold water nice and cold for a long time. Loved it so much, got the 24 one too. Use both daily. Update (11/20/18): 4 months later and they don't keep my water cold even on a two hour car ride. I have only cleaned the bottles by hand and have run the avex tops through the dishwasher on the top rack once and they've lost their ability to keep drinks cold. I contacted Coleman warranty (lifetime warranty against defects) and they said ice retention is not covered under the lifetime warranty. I don't understand that the purpose of this bottle is to keep drinks cold or hot and if it fails to do either of those, it would be a defect, am I right? Why have a lifetime warranty if this is not even a failure due to misuse or neglect? That's fine. I'll be taking my business elsewhere.
