I got it to use with my Aeropress. When used the Insulated mug gets too hot to hold with no handle so I swapped out the Aluminium pot and used my Alpkit mug which fits the stainless steel pot perfectly( so that's one pot of no use. The outer pots the same diameter as my Toaks titanium bail arm pot, which has an handle on, and it fits the Soto bag perfectly even with the both the handles attached.( so that pot is of no real use to me now) Whats left works great. Should have researched more.
Took a little while to understand the process of using these items, the main 750ml pot should be used for cooking. With the other two used as serving containers or as one container & thermal barrier from the inner one cooling down to fast. Very nice quality & I brought two full kits.

Takes a little understanding what you can do with this kit. However you use the main 750ml pot to boil & cook. With the other two being used for separate drinks or a single user one inside another keeping the main container from getting cold. So thereby offering insulated food container.
