Know anything about SeaLift Flush Mount Pop Up Chocks?

[HomePort]

Hi,

I need to install chocks on my hydraulic swim platform. I've been researching my a$$ off and have found that SeaLift sells their flush mount chocks separately. They promote that they can easily be made flush when you want to use the platform. But, "easily" and anything related to chocks/davits/swim platforms rarely go together.

I've included a picture so you can see what I'm talking about.

Anyone have them, seen them, used them, heard about them, etc?

Pros? Cons? I'll take whatever you got...

Thanks in advance.
