At last a company I can trust
I'm very impressed with the design, operation and prices charged by Goshawk.
United KingdomGreat engineering
Easy to light, usefully fuel storage,so no waste, the wind shield is, probably, the most efficient I have found. The stove and shield fit into a 420ml mug and with the addition of a collapsible mug, like the Sto Jo, makes for a nice compact brew system. There other lighter less bulky mugs, I know, but I like the Sto Jo. All in all a superbly engineered piece of kit, well worth the investment.
AustraliaLittle powerhouse
Very impressive little unit. As all the reviews say it boils water like a champion, but pair it with an 8 inch pan and it also cooks a steak impressively well, on a single tank. Has proven extremely handy on my trips when I can’t (or can’t be stuffed to) have a fire. Included stand / shield is a little narrow really for a pan but it handles it well considering the tiny footprint. Probably the best bang-for-buck gadget across my cook-kit collection.
United StatesWell Built!
This thing is awesome! Puts out a beautiful flame pattern and nests perfectly in all my titanium camping cups even my Tito’s 450ml that’s a bit skinnier and not an average dimension. Well crafted and just an awesome piece of gear to have in the kit. It does eat up fuel slightly more than some of my other stoves but it also brings it to a boil faster and shipping did take awhile but it traveled across the globe to get to me. Just buy the thing and definitely get the stand as well!
United StatesSwirling Flame - OP 100
I was impressed with the OP 100 burner and stand right out of the box. It's a good, sturdy build like the Era burner. At first I thought that the flame to pot height was a little low at 1", but then I put it to the test. I used 1 oz of denatured alcohol, 2 cups of water in a Toaks 900 ml wide pot. I gave the burner 1 min. to bloom, then set the pot. I got a rolling boil in 4 min 20 sec. Total burn time was 10 mins. The stand was solid with no wobble and a good grip on the pan. The diameter fit almost every pot or pan I own except for a heat exchanger that fit too close for comfort. One thing to watch is the fine threads on the screw cap. Be careful not to strip them in haste. And, of course, the flame pattern is cool. I call this stove system a success!
