I love, love, love this Owala coffee tumbler! I have it in two colors, the cactus green and the white. I use one for my hot coffee and one for my water every day.Pro; the colors are gorgeous, the size is just right for that hearty morning coffee, it keeps my coffee HOT with a powder creamer I use for about two hours. It keeps my water without ice COLD for about four hours. Of course, it depends on the temperature inside/outside too. The tumbler hasn’t gotten scratched or dented despite falling off the coffee table onto a hardwood floor. It is so easy to clean due to the wide opening. I suggest using either a sponge end or silicone end cleaner as the inside is stainless steel and it keeps it looking nice. Lastly.. the lid is the most wonderful material, quality made with a ‘sippy cup’ style opening to drink from. There is a tiny air hole on the cover which does not leak, neither one of my coffee/water tumblers leak for that matter, lid is not screwed on but pushed down. It is very easy to care for with no extra parts to clean besides the tumbler and cover.Con; The only improvement that I can see this coffee/water tumbler could use is the wonderful and much loved lid to have a way to close up the drinking opening. Perhaps a silicone stopper attached to the tumblers?Thank you Owala for making this product and thank you Amazon for selling it!
