Title: Great Insulation
Review: This thermos nissan tumbler has fantastic insulation, and can keep my coffee very hot for up to 3 hours as advertised. My only problem with it is the lid, as it is certainly not leak-proof. even tipping it slightly on it side will cause some leakage. other than that, its great.
