The first thing to say is that the chain guide top on the container is very useful - it's a great idea. (Perhaps the container should be refillable so that it can be used into the future). The lubricant flowed more freely whern it was at (inside) room temperature (rather than the Winter on-garage temperature. Judging by the lack of noise from the chain, the lubricant did seem to do its job well. However - I don't have the expertise to say whether the lubricant flowed to all the places it needed to, nor whether it reduces chain wear in the long term.
