Any experience with Bruntons Sigma Drive?

Hi guys,

I consider replacing current Globe Drivesaver installed between my shaft coupling and the transmission with R&D drive saver: allows to check/adjust alignment without removing it
or Bruntons Sigma Drive: automatically "fixes" a much greater misalignment and allows the shaft to be slipped inside the coupling if prop hits something.

but i can not find any reviews of using those on a trawler or powerboat. There are a fair number of happy saiboat users but with smaller shafts and engines.
Anybody uses this item or knows somebody who is using it on a trawler or powerboat?

My main reason for replacing is because it's not possible to properly check and adjust the alignment with current Globe Drivesaver.

Any thoughts/comments are appreciated.
