Yes,
I have one of these. Came with my boat when I bought her last year.
I was a bit skeptical when first using it as it doesn't look heavy enough to be up to the job.
I almost changed over to the spare CQR when I dragged on Lake Macquarrie in a southerly where I was anchored in silt and shell.
Since then I have used it for kedging, stayed put in 40 knotts at Broughton Island and spent a week hanging off it in winds between 25 and 55 knots at Island Head Creek.
It digs into sand very well and holds well on most other bottoms.
The CQR will be my anchor of choice in soft bottoms but the Excel seems to do an excellent job otherwise.
My Excel has forty meters of chain behind it and then thirty meters of rope.
My CQR sits beside my Excel on the bow and has fifteen meters of chain and fifty meters of rope. The CQR is nearly twice as heavy as the Excel.
A danforth and rode lives in the lazerette.
