i personally looked at those but have not tried them& just as i suspected >> here are some opinions gathered from some that i have talked to before i bought,eleavation was fast & easy but all had trouble swaying horizontally so i opted to go with the stoney point bi-pod polecats,i didnt like polecats when i first got em but after hunting a whole season they are carried in my backpack & attached very quickly & used on all my field guns now, i highly recommend the polecats, i went with the sitting/kneeling version/hope that helps(regarding the tri-pod models,most have been frustrated in a quick hunting setup to get them setup in time)
I have a tall bi-pod for sitting, but wanted something for walking around and for use while standing. I can't stand the offhand position on an animal past about 75 yards.
Last Saturday I was walking and I jumped about a dozen deer. They were about 100 yards walking straight away from me. unfortunately there was low brush between us so sitting was not an option and I did not have a tree in the right position to lean against.
Since I won't take a Texas Heart shot on a deer that is not wounded, that left a neck shot which I did not feel steady enough for a 100% shot placement...so they got a pass.
I have just used a walking stick and rested the rifle on my wrist, but you still need some height adjustment and the Trigger Stick, if it works would seem to be just the ticket.
Edge: I just bought the tall (66 inch) shooting stick set from Natchez on sale. They are made by Shooters Ridge but I have not gotten them out of the box to actually use them. They were discounted so I bought the set. Instead of $40 they were $15 so I did not think I could go too far wrong. I would really like to find a reasonable tri stick set up. May have to try to make my own.
I have the mono pod. I am NOT sure it is Primos but it's about the same thing. Adjustable plastic mono stick. Works fine for a walking stick. But it's not much good for shooting. I used it antelope hunting where you sometimes spot a goat, get out of truck, walk from a dozen to a million dozen feet, and hope to get a shot. Easy to carry but when I try to steady the gun on it, it just doesn't happen. Too wiggly. Need at least a bipod to get a good rest---and even a bipod technically requires a tripod, with the third leg being your body.
Maybe it's just me, though.

I have used a mono pod for years, but the height adj was a bit of a pain. I bought the trigger stick and like the way it works. The only draw back is the weight mono pod is 1 pd and I think the trigger stick is 2.5 pd.
I used the tall one last year, I needed a walking stick because of bad back. It works good. I was surprised that I could use it while sitting If I placed it on a slight angle, the only thing I would like to see is the trigger to need more pressure to pull.
I have the tall Primos; I don't trust it because the trigger is too "light", all too easy to suddenly lower the rifle, just like artway311 said. I also totally agree with Buckrub about its being unsteady. Still, it's better than offhand, I guess. If I hadn't already thrown away my money on the monopod, I'd probably buy the tripod, trigger and all.
