Title: Best Travel Tumbler, but needs a dish washer to clean
Review: I bought this about a year ago and have used it five days a week. It works wonderfully as described with absolutely no drip or leak. The only issue I had was with the cleaning of the head. I was using a wire brush for most of the time until I got lazy and dunked it in the dishwasher. Lo and behold, it came out cleaner than ever. So yes , it can be cleaned satisfactorily only by a dish washing detergent in a dishwasher.
