GS5121LVL Levelling Base

Anybody on here using this levelling base?

I am thinking of getting one to use on my GS5541LS legs under the Mk2 Wimblerley to make setting it up perfectly level really easy. As it replaces the top plate of the Gitzo legs it doesn't add much to the height and it looks big enough to lock down really tightly.

It looks pretty robust but I haven't managed to find one in stock anywhere here in the UK (North East) that I could actually take a look at to see for myself so I ill have to rely on others feedback before spending another £180

Hope someones got one!

I've got the previous version (GS5120LVL) and it locks fine with a 600/4 and 1DIV on a WimberleyII. I can't actually see what the difference is with the new model but I assume it performs the same or better.
