I have one and, incidentally, use it on the same guitar as Dylla's - a Phillip Woodfield GCIII.
I think it's great - compact, easy to use, very adjustable and - as others have said - it can remain on the guitar when in it's case (although I always remove mine).
However, I did have one issue: The large sucker tends not to move but the small one (ie the one that attaches near the endblock) did move when I used it on a CG. It was fine on my steel strings, I suspect because the finish on those is smooth/glass-like. My CG is french polished and this sinks into the wood a little so its slightly more difficult to achieve a completely airtight seal with the sucker.
The solution was simple - the strap has holes in it, just like a regular acoustic guitar strap, into which the sucker locates. I got Phillip to put a small endpin on my guitar and use this on the strap rather than the sucker; the whole deal is now rock-solid.
