What do you expect from a 9 carafe? The carafe is made of glass and has a "plastic" seal, the upper part of the cover is also made of glass. The optics I find very appealing and the carafe is doing very well on my shelf ... I give 5 stars because the price / performance ratio is just right. If you naturally buys whiskey for +100, you should buy no carafe for 9, but for everything else it extends fully.
