Keel guard for Outback

Been thinking of trying to preserve the life of my Outback by installing some type of keel guard.  I've read some of the previous discussions on this topic but didn't see any experiences with a keel protector sold by "One Objective."  Curious if anyone is using this product or has heard any feedback.  There is one youtube video where it was used on a 2019 Outback.
