They are more of a mess than they are worth - especially for today's sportbike chains.
Your o or x ring chain doesn't actually require any internal lubricant, as it is sealed by the rings.
The auto oilers will just require more chain maintenance as you will be constantly cleaning it, or replacing it due to the dirt that has been attracted by the oil ruining your chain.
Before the internally-lubed o and x ring chains, this system was a great idea, as the chains truly required mucho lube, now it's unneccesary.
