So I flip the can so the gas feed tube is immersed in the liquid in the can and the liquid is vapourised in the preheat tube. Without the preheat tube and the ability to flip the can I reckon they'd be very average, they are designed to be used in a box stove where some of the heat from the stove helps vapourise the butane.
I use a Kovea Spider because it has the preheat tube and a hose and it's light and cheap. I'm not a fan of the pot rests, they are a little slippery, you have to watch your pot doesn't slide off. I think I'll use a file to sharpen them up. I wouldn't mind trying a Kovea Hydra, that is liquid and gas fueled, but I'm already at N+5 when it comes to stoves.
One thing to watch for is that not all butane adapters are created equal. I started out with a cheap one like this https://www.ebay.com.au/itm/Camping-...MAAOSwrFBdeLtn, but eventually the plastic prongs started wearing out and it wasn't fully opening the cartridge. I thought there was a problem with the stove or the gas until I eventually pushed the adapter in and lo and behold, fully functioning! On that trip I used a rubber band to hold it on, but I now have one similar to this which seems a little more robust https://www.ebay.com.au/itm/NEW-LPG-...item441457cf17
