After reading reviews and comparing ratings vs cost, this reservoir stood out the best. I bought the 2L model. I haven't gotten a chance to field test it. The build looks good, the bite piece closes up well, not sure how long it will hold up through constant use though. The dryer arms are kind of useless. I left it out to dry for a day, still was wet inside. The hole is a good size so it would be easy to clean, unless you have freakishly large hands. Can't wait to take it out and put it to use!
