I've decided to sell this as I prefer to use the standard ball head on my tripod. The one I have has the yellow trigger rather than the black as shown in the attached specs. Works perfectly, couple of scuffs, complete with quick release head. Will take a couple of pics when I get home.
Most places seem to have these at £100 plus delivery but as I got this as part of an ebay purchase I'm not looking for anything near that. £45 including delivery is reasonable I think.
