This is a quick overview of the BRS 8B. I have not had time to fully play with the thing as my reviews take 6 months but as there is lil info about this top of the line Chinese manufactured Multi Fuel stove I thought I would make a post here. I have used other Chinese multifuel burners such as APG, Jeebel Camp and other clone " Insert random english name here... " I have got to say this although looks the same really is a great improvement versus the Chinese competition. Basic specs. Weighs 545g with the fuel bottle given which is like the other BRS products a 530ml bottle that should only be filled upto 450ml. Stove stand minus burner and preheating tube weighs 187g. Pump is a BRS-8 BRS-27 Pump which is specific as of now only for this stove system. It has two stages , should be green and has P AND B. You have to twist the fuel line on to the fuel bottle intake without using the knob which does not rotate. see pictures to tell the difference. 1ltr bottles were purchased separately. How it works? Unlike the other Chinese multi fuel stoves that require pump, relief, light, preheat for 30-60 secs, then blast on the relief valve, this one is peculiar. If you have used a Soto Muka, it is very similar preheating operation. make sure relief valve is closed 1. Set knob notch to P. 2. pump until knob relief valve, which is the indicator for the preheating air intake system shows or denotes a red ring. 3. release relief valve about halfway to full.... 4. light as soon as possible and adjust to full ..... ish. You will have to fiddle with it. ( It will come out pressurised, that is fine and how it supposed to be ) 5. switch the knob on the green control knob from P TO B..... Then lay fuel bottle on its stand. Know that it will sputter tiny bit with yellow flames, i spoke to the manufacturer a while back and they have said that is how the preheat works, it is pressurised to turn into a near vapor state when once heated helps to heat the whole tube and fuel line turning the liquid into vapor faster. on 91 octane & 95 octane on the old style Chinese burners, it takes about 40 seconds to go from sputtering to easy to relief the valve. This new system takes only 20 secs maximum in my tests so far. Because the preheat is when it is on, it helps with the heat to heat the whole assembly faster to get the fuel to ideal vapor conditions. Versus, relief a lil, ignite, wait for a min or under, then relief to whack it on full bore. NOW IS IT TRICKERY? A marketing scam. The system so far with petrol does work, yet to try with other fuels but for its intend function YEP super awesome. Kudos to BRS for a thought out design. Conclusions I look forward to rigours of hardcore Bushman testing in the dirt with this. Just a great change compared to other Multi Fuel burners. Build quality on my unit is exceptional. Design whilst use base parts is well thought out for its designers intentions and use case. I purchased this with GST for $ 136.78 NZD on ALIX ( Taobao is cheaper) which is pretty decent. I bought this for the features more so then the " But it is cheaper " part. PROS: Lighter then some other chinese multi fuel burners. Faster preheat by half. Fuel line is at a swivelling right angle, it rotates and is not just stuck in a fixed position. ( See pictures ) Seals are better, with tighter clearances on all contact points of fuel lines. CONS: Tool does not work for nut fixing the burner assembly to the base stand. A learning curve. Unusual operation order due to preheating system. Needs to have the hole for ignition to be larger although DIY will fix it to make it easier for a match, ferro rod sparks or lighter to ignite the " vapor " gas when it is on ready for go time. Stand is overkill for most pots, to large, could be a tad smaller.
