Review on OKADI Large Coffee Thermos Travel by Chris Munns

This could be a good product for a small business as it holds 2.5L and pours coffee into cups fairly easily. I found it good for about 5 hours which may be enough for many. If you have a microwave handy, it might not be a big deal to keep it hot, but I also like hot coffee in the afternoon and don't have easy access to a microwave at work. The top opens well, but I can tell that a lot of heat is lost due to the poorly insulated plastic cover. I also doubt the plastic latches will last very long before the top hatch snaps into place. A better idea would be to just have a screw stopper, which is a vacuum stopper with a silicone seal, and cut the side to allow the screw to be partially opened to release the coffee without as much heat loss and reliability issues later. I returned this item and am sticking with my plain 40 oz thermos which is fine and I may get another one and two will be better than one of these thick ones.
