I have been shooting the bigger model called the Spec-Rest and am very impressed with the results. The Spec-Rest is a bigger unit, based on a very sturdy tripod. The rifle is secured into front and read holders and three controls are available for aiming. First there is a lever on the central stem that controls horizontal movement. This lever locks hard when you need to steady-up the rest. The other two handles control vertical movement - one enables large amount of movements quickly, and the other is a super-fine dial that lets you split hairs. After some practice I began shooting groups that I did not think possible from the standing position. Best three-shot group at 100 yards was 0.609", had two more under the inch mark. This is a precision shooting rest, the best I have ever shot standing position from. Will work for kneeling/sitting also but I have not tried yet. Not light, not small. About 28 pounds so it is for hides and blinds. Could also be used from a pickup, after seeing a critter one guy could get it out of the truck and set it up while the other guy lasers and gets his rifle ready. Plan on taking it on a Montana p-dog shoot shortly, will be interesting to test it on long shots.
