I had purchased the 1.7 liter Reactor previously. I purchased the 1.0 liter pot as a smaller/slightly lighter option. It works great, as you can still fit the burner unit and the smaller fuel canister in the pot for transport. The burner unit is a "snug" fit, but if you line up the fuel control lever with the "pour spout" on the pot, no problem. Great stove.
