Stick with it, a brilliant product, which will definately prolong the life of your chain, especially if you ride in all weathers. I've had them on various previous bikes, but you do need to ensure propper adjustment. This can only be by trial and error, if you have excess lube - simple turn it down!
Propperly adjusted it will have less "fling" and mess than any other type of lube.
Having said all that I wouldn't fit one to my new Darkie
I love cleaning it. It's also akin to fitting a topbox
