I am impressed. All moving parts have tight tolerances. Excellent for backpacking. Small and light weight. Will not rust. Does not leak when moved around. I bought the storm lantern style, and it does stay lit in a 7 mph wind as advertised. Unlike other oil lanterns this size, the filler cap fits and seals perfectly. The small globe would be difficult to break. The flame spreader works beautifully to produce a 1 in. X 3/4 in. (2.5 cm X 1.9 cm) flame--impressive for a 1/4 in (6 mm) wick, even when burning diesel fuel or other heavy oil. Does not require precise trimming. I let the lantern burn out, and that trims the wick perfectly and burns off any crusty residue. I get 13 hours burn time using diesel when set on high and twice that on low, so it provides heat all night in a small tent. Expensive, but I expect this lantern to last the rest of my life.
