From buying this pot I have to advise against. I had in two years (2-3 uses per week) two defective automatic buckles - the second last weekend was particularly annoying, the bottle ran out in my backpack. The 5-year warranty, with the product being advertised, refers lt Alfi only on "the outstanding insulating properties" of the bottle -. As she will not reveal to me - still exist in the opinion of the manufacturer and with a defective lock. So who is willing, in addition to high-priced pitcher about once a year about EUR 8, - to spend on a closure and in addition will take the damage from leaking fluid into account, to buy the part. I'm going to look for something Inexpensive ...
