Title: Leaky
Review: I got this as a gift. Looks and feels great in the hand and keeps liquids both warm and cold so it is very functional in that regard. But if you want a leakproof tumbler, this is not it. I like to put sugar and cream in my coffee and then shake it just a little. Every time I shake it everything pours all over along the seam where the top screws on. Even if I let out a little pressure. The inside threads are an issue as well since the coffee shops just don't listen and if filled up you have to pour an inch out so the top will screw on. Poorly designed and leaky. I think there has to be a better product out there.
