They are lash-ups. Everything from someones high school electronics project through to hospital syringes and fish tank hose. The environment at the chain sprocket interface will make a surface protection/paint/adhesives engineer sit sucking his thumb rocking back and forth in the fetal position, it is no place for 3M pads and cable ties. If you are lucky they stay put and apply something like a suitable amount of suitable lube. If you are unlucky they get cut to pieces when they lose out in fight with the chain, drench the tyre in a unsuitable lube or do nothing and give you a false sense of security.

I will not have another. Scotoil was the wrong lube, too sticky, never going to do anything more than stick dirt on and make grinding paste. Engine oil rotted the seals on one of the fish tank hose and syringe contraptions and a bit of WD-40 can straw bosticked in was never going to control the flow. Both cost more in time and cash than I'd have spent with a rag and oil can or stripping the back end of a Bavarian Behemoth to get at the splines.

The correct current solution is the factory made, bellows design chain case MZ used. Industrial chain lasted 100k+ miles. I hope the BMW teflon/diamond works. Until then is it really so hard to wipe it with an oily rag?*

*I don't use spray cans, sticky is bad. Tot up how much you'd pay wurth and you may as well just buy a new chain when they wear out. These things wre consumables, so consume them.

Before buying an oiler do a lifetime cost analysis. I'd have to successfully transfer the same oiler from bike to bike three times.
