I'll have to compare this against that other brand. Both are listed at 700ml, seem well constructed, can fit a small stove w/ fuel can, an alcohol setup w/ little bottles, easy enough to clean w/ large hands and has a functional lid. This one doesn't have measurements, but it holds a nalgene bottle better (think air wooshing when you separate them).
I can't tell which lid I like better. The other brand can kind of attach to the body when not in use and has holes closer to the edge for easier straining. This one has an interesting handle that can slide around between grooves. One set of grooves is for storgae and it doesn't really lift up. The other groove tilts the handle up and away from the vent holes. These holes have less room for steam to escape.
I would say that this works with the JetBoil coffee press better. With the other brand, you had to move the fins out. Even then, you had to get the right angle to get the seal on a cold pot or it would just fall down. For this one, minimal fiddling with the fins toward straight down makes a perfect seal. If you want to jerry rig something else, a Bodum Chambord press seems to work, too.
I started w/ a GSI Pinnacle Soloist w/ a sea to summit x-mug. I wanted another boiling or campfire option and bit on the sale price. I'm pretty happy w/ this purchase. After fiddling w/ things, my current setup for 2 people seems like a perfect nesting system:
-> hold the Soloist bowl open side up
-> put the bottom of the non-bagged kettle in the bowl
-> foon, alcohol stove, windscreen, some fuel and a lighter
-> kettle lid
-> x-mug downward
-> the upside down Soloist pot over everything
-> flip everything over
-> gsi pot lid & lock the handles
The other way around seems to have the pot lid squishing the x-mug.
