“I've been using a Yama Siphon daily for several years and occasionally break the top part.
I noticed that this one is made differently from previous ones, it has a seam connecting the tube to the brewing chamber.
I was concerned about how heating might affect the seam, but nothing has happened after several uses.
This one works great with my favorite type of filter, a Cory glass filter, it lets hardly any sediment escape to the bottom and hasn't stalled yet.”
