The main problem with connecting a gas burner directly to the top of a gas canister is that the result is an unstable cooking system due to the height of the pan when placed on top. Also, to control the flame you have to position your hands directly under the pan of boiling water. A safer option is to connect the burner to the gas canister via a hose, with the flame control now being located on the gas canister. The best example of this design in our test is the Primus Express Spider. It has a 16cm diameter pan support for larger pans and is extremely stable and easy to use. The price is particularly competitive too and when packed away it takes up only a little more space than a top-mounted gas burner. Personally I would much rather use this type of gas stove, particularly when wild camping where level ground is less easy to find. But the price you pay for the increased stability and ease of use is a little more weight. While 194g is not heavy, a similar direct-mounted gas burner is around 50 per cent lighter and there are lower-priced options too. Like all gas burners, with the Primus Express Spider the performance drops off as the gas is used, but as with all the hose-mounted burners performance is slightly slower than a top-mounted stove.

If you like the ease of use of a gas burner but want more stability, the Primus Express Spider is the perfect choice – provided you can tolerate increases in weight and boil time.
