I have not yet bought this mount but I will one day. I have a lot of Lansky sets, Diamond, De-Luxe, Serration and a Sapphire polishing hone. What puts me off is the price, you can get this cheaper on the beararms website but it's still very expensive.
A Lansky Universal mount is half the price and should be included in the De-Luxe kits anyway, there is even space in the boxes for it! One or other of these clamps makes it a lot easier and less tiring to use the Lansky system if you haven't access to a vice in a comfortable environment.
My choice is Lansky Pedestal Mount
but not from this seller that wants £8.50 postage! Try the beararms website, they are importers of Lansky systems and hones.
Anyway the pedestal mount stuck onto a chopping board is my choice maybe not the best but I've sharpened hundreds of blades on it with only a little wear on the pivot, nothing a bit of tape won't solve.
Until the day when I eventually shell out the money for this admittedly wonderful clamp I'll get by with my alternative, I hear that they've released a leather "stropping hone" for about half the price of the C mount, I think that's next on the list for me.
**** I've knocked a star off because there should be a mount of some sort or even a half price offer with the De-Luxe kits. Oh and the high price. ****
