As with the one reviewed by someone else, the compass did not work on my pole either, hence 4 rather than 5 stars.
Even so, the pole is very good value for money. It is an effective walking pole, being light, having good suspension - which can be turned off - and seemingly well made.
It is not a bad monopod either. Used this way,I suspect it would work very well with one of the new 'travelzoom' compacts and would, therefore, be very useful to someone wanting to record a distant view from the peak just conquered with a the long end of the zoom. I gave it a much tougher test because I used it with my Panasonic L10 SLR body (fairly compact and lightweight as digital SLRs go), its very solid Leica 14-55 mm image stabilised standard zoom and appreciably lighter Sigma 55-200mm non-image stabilised telephoto zoom. It says quite a lot for the Cammlink that I got some sharp pictures using the long end of the telephoto zoom at 250th of a second i.e. about a stop advantage over what I would be confident hand holding it at. (Due to the smaller than average 4/3 system sensor fitted to the Panasonic, the range of this lens is 110-400mm in 35mm speak.) With the standard zoom, the gain is much the same, not greater perhaps because the centre of gravity of the camera/lens combination is further forward.
Putting this in context then, the Cammlink can be guaranteed to give one an extra stop advantage over hand-holding. My much heavier and four times as expensive Manfrotto monopod will give me an extra 2-3 stops and take heavier camera/lens commbinations, but its a pretty lousy walking pole.
