What do you mean by "success?" The only thing that an airlock does successfully is to vent excess co2 so you don't paint the ceiling with your beer.
It's a vent, a valve to bleed off excess co2, it's not a fermentation gauge, it works "successfully" if you don't have an explosion....NOT if it bubbles or not.
Beers ferment no matter if the airlock bubbles or not.
Many folks just cover their fermenter buckets with a piece of plexiglass letting the co2 push out between where the plexiglass and the bucket meet. Others cover their carboy mouth with tinfoil. Totally ignoring the need for either an airlock OR a bucket cover.
A lot of folks, especially folks with arthritis, barely even put the lid on tight at all, they just lay it on top. again, if co2 is getting out, NOTHING nasty can get in. And that really is all that matters.
So all airlocks work, as does blowoff tubes, or using plexiglass, or tinfoil, or saran wrap, or just setting the lid on loosely.
