Review on 12Oz KETIEE Travel Coffee Mug - Spill Proof, Insulated & Reusable W/ Seal Lid - Hot/Ice Tea Compatible! by Josh Cardoso

The travel mug I received was not leak proof. Others may be? This why I purchased the mug.For me, after multiple attempts to fill travel mug correctly to prevent leaking coffee (half-full/ 3/4 full, different levels - all unsuccessful), I decided it was just too much effort to try and solve or for the early morning rush to get out to work.I do like the idea of a solid interior (one piece molding) and the easy open/ close lid. I ordered the 12 oz., 2A - Green travel mug. Fortunately, easy return.
