I have a PDOiler and am very impressed. Better than tutoro and scottoiler IMO.
I had a tutoro auto on the last bike and while it was initially ok it eventually stopped supplying oil which I heard a few people say. Think you need thin oil and keep it well maintained.
I have it setup oiling the top of the chain and in use the entire chain has a nice fine layer of oil over it with no fling or excess and no rust at all.
Slight rust on side plates is isn't actually a worry though (although shouldn't happen if properly maintained), due to O-rings protecting the joints, its the rollers you need to be oiling for the contact with the sprockets.
