I had one for my spotting scope/video camera with backpacking/hunting. Had it for about two days, then I took it back. (I'm assuming you're talking about the one with the pistol-grip head) It seemed sturdy in the store, but in the woods the slightest touch and 60x was rendered useless. Even at 20x you really couldn't have a hand on the scope or tripod. Also, the head was not solid enough to hold the scope in position.....for instance, if you put the tripod+scope over your shoulder the scope would pull the head down (if that makes sense, also I'm not using a giant scope...its a Nikon fieldscope with the 60mm obj.). I took mine back and got the Manfrotto pistol grip and Manfrotto carbon fiber tripod. This setup is a little more expensive but is hands down better. It is slightly heavier but is well worth the little additional weight. VERY solid, and the pistol grip doesn't budge....unless you want it to.
