The Nemo oiler on my 1190 flings almost no oil at all.
Opinions differ on this*, but my opinion is that some lube is good to stop surface rust and keep the O rings supple. Lubing the rollers and their contact with the sprockets can't do any harm either. My lube of choice is gear oil, which you need to apply at fairly short intervals, so an oiler is a good solution.
*From perusing many forum threads on the subject from firmly entrenched points of view from both sides, it would appear that chain life is little affected whether you lube or not.
