This is a rare canister stove for me as I had missed being able to buy one new and Optimus current lineup doesn't have a four legged version of the Optimus Crux. Fortunately I was able to actually find one at a completely reasonable price at an auction and it was in a pretty okay used condition that wouldn't have hurt any more than if I were to have used it myself for years. It is a bit more of a beefier stove that lacks all the "weight saving" features like the control valve block being cut out and has a slightly more complex locking mechanism on the rotating head where it locks on the inside and bottom surfaces rather than on the outside. I don't think it reduces wobble by too much as it still does wobble a little, just like the external nuts used to hold the tilting head isn't any different beyond being less obtrusive. There is even a nice brass insert for the thread rather than being just coated aluminum. However from just setting a pot or wide pan on it the stability difference is definitely there! 4.75" diameter from the tips across and 2" leg to leg with the nearest tip to point while the tip to tip is 3.5". In contrast the Crux has about a 4.5" diameter and the nearest tip to point from the tips is 3", tip to tip from neighboring legs is 3.875"! The four legs makes it a lot more stable like the Soto Windmaster with 4Flex, Soto Amicus and Snow Peak Gigapower GS-100 but it doesn't hit the Windmaster's crazy 5.625" diameter with the 4flex supports. Too bad Katadyn/Optimus doesn't produce a four legged stove like the Flex. It would make sense if the Crux was the four legged stove in the lineup while the Crux Lite remained a 3 legged stove but from seeing how the legs are bent and longer I get they're just using the same legs between the Crux and Crux Lite. Curiously it is Made in Japan. Flex pictured on the left.
