Review: Yeti & Thermos are no match! - Moved over Thermos Stainless King & Yeti Rambler. This Ocean Bottle Drinking vessel is better than both. I know because my wife & I have had both and returned both. Ocean Bottle keeps drinks hot for 6 hours. I know because we've tested. The drinking from these Ocean cups is easy and clean. No mess, just good, easy supping. The turn tops to lock keep drinks inside with no drips or leaks. And the tops come apart in two bits for deeper cleaning. These aren't as rugged as the Yeti Rambler but they are far superior in terms of retaining heat and for overall usage. The yeti kept our coffees hot for 2 hours tops. The Thermos was better at around 4 hours but drinking from them was awful and awkward. I'm not sure what the low rating reviewers are on with their poor reviews of these Ocean Bottle vessels. They are superb, worth the money and possibly the best travel cups for coffee on the market.
Review: Still perfect 9 months since purchase. - Keeps drinks hot for a good 6 hours (maybe longer, I've not tested) even when the outside of the bottle is really cold to the touch. It hasn't leaked at all, so perfect to put into my bag or lay down. Used everyday for coffee since my 1st purchase back in January (9months). The brew flask lid (the only lid i've tried) is good to drink from unlike many flask / reusable bottles. Dishwasher safe and hasn't faded in colour. Great fit for my cars cup holders.

### ⭐⭐⭐⭐⭐ Drink is hot for hours.
*by S***T on 14 August 2024*

Bought for my wife’s travels to and from work. Excellent t quality. No leakage, lid can be turned to allow drink, then further turn to remove to allow cleaning at the right time. First time using be careful as both the wife and I nearly burn ourselves with the drink. Drink is hot in the morning and can still be after lunch. Size - holds a cup full and plenty, but other sizes are available. Great color options. I and my wife have one, a very welcome addition to our commute or outdoor trek. Highly recommend as not seen a cup as good.
