I have the wally world bipod and it works very well for me. I mainly keep it on my Ruger 10/22 but I do switch it to my Winchester 243 and will be using it on my Savage 222 after I install a swivel stud on it. IMO the set up and ease of use are exceptional for a 40 dollar bipod. These bipods are adjustable the only thing is that unlike a Harris you only have one set ring in the legs and this is at it's full extended length. to adjust the bipod for uneven surfaces or a shorter height the wheel on the legs must be turned and it will hold the bipod at the height that you set it at.
