Nice review. I was surprised that nobody had commented since you posted it in September. I just "discovered" this product from reading another thread here on AGN, though the first gen model has been out for quite a while. I was a bit skeptical since it is so light weight, but I found it sturdy enough for a 10 pound rifle. I usually use a tripod with a ball head on it and an Arca plate on the gun, but the Trigger Stick can be set up in a fraction of the time it takes to set up a regular tripod, particularly if the tripod legs are in the closed and retracted position. Once deployed, changing to a new shooting position is instantly done with the Trigger Stick tripod.
There was no mention of the 1/4-20 screw camera mounting plate being bundled on any of the web listings, so I figured I would need to order one separately, but was pleased to find the plate came with the Gen3 tripod I bought. It is handy to attach a spotting scope or a binocular mount to the legs for spotting.
While I was waiting for it to arrive, I watched
YouTube videos on how to fix sticking legs when they stop moving on their own and was expecting to have to force the epoxy glued on caps on the top of the bottom leg sections off to get inside the legs for cleaning and repair work. It looks like Primos either pays attention to YouTube and customer feedback and has changed the way they are attached, the new system made assembly at the factory easier and less costly, or both. The Gen3 has some tab locked caps rather than glued on caps at the top of the bottom leg sections, making it very easy to remove the caps, exposing the locking mechanics inside for cleaning or repair. I will post some photos later of the new cap design. With the easy off caps, if you get mud, dirty water or sand down inside the legs, you can quickly remove the bottom section with nothing more than a pocket knife or small screwdriver to release the tabs, flush the insides with clean water and you are good to go.
Don't lose or damage the white plastic (PTFE?) split ring that is in there if you remove the bottom section. Some of the YouTube videos stated that the white ring was "broken" on their tripod and threw it away, but it came that way from the factory. As you reassemble the legs make sure the white ring is flush inside the groove as you slide it back over the upper leg section or you will end up messing it up. I don't know if Primos will sell spare parts for these. Others have mentioned that their customer response in the past to sticking legs with the glued on cap Gen1 was to buy another tripod. With a few minutes of your time and minimal mechanical skills you can fix sticking legs even in the field and continue to use it.
