Oil filled hubs? (I.e., Vault hybrid lube systems)

Anyone have this type of lube system (vs traditional grease) for your wheel bearings? VAULT HLS Maintenance Free Hybrid Oil Hubs by UFP Trailer Buddy

Many boat trailers have oil bath systems. I'm not sure about that specific type, but my boat trailer has a little sight window where you can see the oil level.
Seems to work fine and is sealed to keep water out. But they do require oil changes periodically.

Most class 8 trucks use an oil bath system for steer and trailer axles... its functions very well and during the walk around (daily safety check) the driver can pull some of the rubber plugs and check the oil level... or if the cover is clear, he can see the oil level that way....
