Sorry to start another stove topic. I see there are many already and I've been reading them, but I haven't seen too much discussion on Gravity MF II.

At first I was looking to buy the OmniFuel because in general it receives very high reviews. But the Gravity MF II is 100 grams lighter, cheaper, supports all the fuels of the OmniFuel and so far got good reviews:

Does anyone have experience with Gravity MF II vs OmniFuel? In particular reliability, simmer control (OmniFuel is supposedly superb at simmering), noise?


To complicate the choice I was also considering Nova+. I've read this thread [url=]
and many other reviews that say it's a good stove. I then found this site: [url=]
and if the measurements are correct, the Nova+ is extremely quiet. However, there are several claims that when you disconnect the hose from the bottle there's still fuel left in the line that leaks out - even with the flip bottle shut off that should get rid of the fuel and depressurize the bottle. Is this true? How about the Primus stoves? To me this would be a major annoyance.

I have the omnifuel and am very happy with it. I know the gravity ef (the gas stove) and it's a good one. Few things - as much as I know you can't really simmer with the gravity vs the omnifuel that simmer very well for a liquid fuel stove. The folding lags with the gravity - it's ok but nothing like the stability of the omnifuel - if you really want to save weight - great. but if you want it to be as strong as it's get - go with the omnifuel.

I don't really know the nova


fuel in the line - not with primus if you tern it off with the OFF will get few drops around the screw connector

I have an older Optimus Nova, and it does not leave any fuel in the line. I have no experience with the Nova+. It runs like a champ and is a lot quieter than most liquid fuel stoves.

Thanks, in the end I ended up going with the OmniFuel. Gravity MF II wasn't in stock and I needed a stove.

I decided against Nova+ because some reports that the EZ-connector fuel line broke. It just looks more rugged on the OmniFuel.

So far no drips in the fuel line when disconnecting - very good. It's loud, but it boils fast and really does simmer to a candle flame, so at least the noise isn't for an extended period of time.
