aqualung sos

[hydroslyder]

I have seen a lot of people saying that a safety sausage is an almost necessary peice of equipment. I have a sea quest pro QD+ BC, and was looking at buying the aqualung surface observation signal, but before I bought it I was wondering if anybody has used one of these...

How well does it work?

How easy is it to use?

Does it restrict the flow of that exhaust valve?

Is it truly almost hands free?

Etc etc

Thanks
