I have been using one for years,, honestly I think its the best ground seat available for function alone because what other seat will let you shoot 360 degrees with no sound, what other seat can you actually lean it in different directions for a better shots.
also like Sean said put it in the ground about 10" away from a tree then lean back for a nice recline but when a deer comes in shoot right from that position or lean forward and turn for any angle shot and now the tree isn't even there to bump your drawing elbow on,,, I can shoot directly behind any tree with the nifty just lean it forward then to left or right,, your legs do all the steering work.
I adjusted mine to my preferred seat height and loc-tighted everything, I chucked the case and instead tie para cord from the stand itself to carry over my shoulder like a possible bag then the stand lays over my butt behind me when going in or out,, I have a extra sheathed knife and a couple pens (for deer tags) taped to the base above the big washer with dark hockey tape just in case.
I get exited when I hear about these 8^)
