Fabulous!
I like the tea in my very tall travel cup extremely hot, so plastic straws that melted were not an option.  Hummingbird crafted a 12&#34; long, high quality glass straw--meticulously packed with a cleaning brush.  Sipping hot liquid through glass straws versus plastic is an adjustment; I recommend colored straws to avoid minor collisions with your teeth while driving.  I'll be ordering more with confidence!
