Just received a set of the tripod version, and I have to say, they are sturdy and not too heavy at all really, so on the whole, I am very pleased. One criticism would be that there is quite an audible noise when extending/closing, caused by friction between the two tubes of aluminium. I've tried wd40, but with little effect, it feels as though it could do with greasing internally but it doesn't appear to be dispmantleable, anyone else had this or got any suggestions?
