Love this travel mug! I’d previously picked up the Contigo here of the same size, and it kept my coffee or tea hot but the lid was such a big, cumbersome contraption - and after about 2 weeks everything I put in it tasted like plastic. (I soaked it as directed, to no avail.)
This SIC tumbler also has no seam inside (the Contigo does.) I feel safer drinking out of that. The lid is clear plastic (I believe it is BPA-free) but has held up fine so far, and it has just one movable piece that pops out in a second so you can clean it.
Very happy with this (and the 27 oz bottles.) I’d never heard of this brand, but I’m glad I took a chance on it. Highly recommended.
