British product for MOB retrieval

[SFS]

Has anyone ever used an MOB Life Saver? It seems like an easy-to-use, always-available solution for MOB retrieval, for about $25 per person.

I first became aware of it watching videos from Duncan Wells ("Stress Free Sailing") on Youtube:

I am seriously considering ordering two of these for our autoinflating PFDs as we begin cruising. Anyone used them?

I have no affiliation with, or interest in the company.

Havent used this one however we have another great British technology aboard our yacht... a Jon Buoy. We’ve only used during a trial to familarise ourselves but it works as promised.
