Title: A shame....great design but horrible taste makes them unusable
Review: Have to start by saying I bought three of these and my family really likes the design...comfortable, keeps contents hot, doesn't leak...very pleased with design. However, all three tumblers have a terrible taste and cause the contents (tea, coffee,) to be completely undrinkable. At first, we each thought it was us or something was wrong with the beverage...but then we started sharing experiences and realizing that we all had stopped using them for the same reason...the just awful flavor that leaches into whatever beverage we put in. We did do some little tests to make sure the beverages tasted ok before we put them into the tumbler...and they did...really not sure how to understand this. Very disappointing.
