I own both the windmaster and the amicus. The wind protection comes from 1) the design of the burner and 2) the shape of the ring below the burner. Both stoves far outperform any MSR or Snowpeak stove I have ever owned including the Litemax in boil times and fuel efficiency especially in the face of wind. You will still need to find or build or carry a aluminum foil windbreak especially to light the stove. There are some excellent performance tests published by Hikin Jim at https://adventuresinstoving.blogspot.com. Buy this stove. You will be happy.
dawongerThe Windmaster is manufactured out of "titanium" and with its triplex pot holder is 2.3oz according to SOTO. The Amicus is manufactured out of aluminum and weighs 2.9oz. The Amicus packs up smaller and is easier to deploy the potholders since they are attached. With the Windmaster the pot holders are detached. The fourplex has four supports under the pot and is more stable with a heavier pot. I have used the Amicus with pots up to 1 liter and 1.3 liters with no problem. I think the Windmaster had slightly faster boil times than the Amicus when I did my backyard testing. But both the Windmaster and the Amicus beat the SnowPeak Giga and the SnowPeak LiteMax.
