Fantastic stove! I'm not a fan of the current "stacked" stoves with pot over burner over cannister, they're so unstable its a hazard, hence updating my old Primus Easyfuel 2 with this.
The stove itself weighs 219 grams, pump is 103g and supplied fuel bottle is 87g. The stove is smaller than the old Omnifuel and now fits nicely inside a 1 litre pot (Primus/ Optimus etc) to keep it tidily packed.
Having done some calcs it seems the stove burns Primus power fuel and gas at the same weight per minute (using correct jetting) and each fuel is almost identical in efficiency for boiling water, with gas using 2.4g/min and powerfuel/white gas using 2.49g/min.
In terms of overall pack weight, with one 250g gas cannister it weighs 600g (new cannister weighs 380g!) and using a full fuel bottle weighs 707g, although with the bottle you get 300g of fuel rather than 250, hence on anything more than an overnight trip where you'd take a 100g gas cannister it is more space, weight, cost and time efficient using liquid fuel - and the liquid fuel doesn't suffer depressurisation slow-down like gas cans do, as you just give it a few more pumps on the handle.
Overall a fantastic, light and efficient stove, not to mention the titanium grin factor!
