I have seen these seatposts on ebay under various names. They claim low weight and even with postage from HK to the UK they are quite cheap.
Has anyone used one for any length of time and if so are they ok?
I would be a bit concerned over the unusual clamp design. It looks like the saddle rails would be held on 2 quite sharp edges. With modern lightweight saddles often having hollow rails I wondered if this could cause damage.

The other option I was looking at is the pump post and possibly removing the pump mechanism. Has anyone done this and if so does it save much weight?
thanks
