Is this mug easy to cleen? Especially the mouthpiece area.. does it have complex mechanism and parts that dirt can clog inside the mechanism or is it simple rubber and hole seal?
EliadI own one of these. It's got two gaskets, a rubber head, and a mouthpiece. All are easily removed and logically reassembled, and every part can be easily cleaned except for the mouthpiece tube, which you might need a pipe cleaner or something to reach properly.
