I use the ULTRApod I (yes I, not II) For more than 10 years. In the Sahara, the Himalayas, at + 50 ° or -30 ° in Australia in Scandinavia. I've never used it with my compact camera (for I have an even lighter and shorter tripod), but always with my Canon SLR (analog EOS 500, Digital the EOS 400D). With the 18-55 zoom lens that I ULTRApod in every imaginable and unimaginable holds bombproof position. With the 300 Zoom will be a bit wobbly, but that's up to the damn physics ... One just needs to tighten the locking screw and to prevent the camera budge. The ULTRApod I plugged in my camera bag in the included and so is always there. Accordingly, it is often in use. And no matter where you stand attached it to the big cactus in the Mexican desert or on the ice ax in the hike - never disappointed me has it. I'd never trade it.
