I was given the Primus ETA solo as a gift. The stove, wind screen and pot with the heat exchanger and lid weigh 15.4 oz. The size of this "solo" set is awkward - almost too much for one person, yet too small for two.

The solo set up that I use: titanium solo pot, lid, SnowPeak stove and 1 oz home-made wind screen is 8.8 oz. If I instead use the small Evernew pot the set up is 10.3 oz.

The ETA solo set is 6.6 oz. more than my current solo setup. I have not used the ETA stove yet so cannot comment on it's efficiency. When I added my 1oz. windscreen to my Snow Peak stove, I got about one more days from a medium sized cannister.
