I have one, and it serves its purpose. I basically just keep it in my pack when I am doing hunts that I don't really plan to glass tho. (Archery hunting mostly)
When I end up in a spot that I wasnt planning on but have glassing capability I'm glad i have it. It can be a little tougher/slower to adjust the legs on trekking poles depending on what style you have, I would say lever lock poles would probably be better than twist lock (I have the s and s twist lock.) It can get a little tough getting them out at the right angle to match uneven ground. Overall I am happy with it, but if I'm going to be spending a lot of time behind the glass, then my slik tripod goes with me.
To be fair, I have not used it a ton for a more in depth review, but have used it some and that's what I have noticed so far! More testing will be coming this year!
