I have two of the higher versions. I think I got them at Campmore(?)
When lightest weight is not the issue, I have brought these. A couple caveats, though.
1) Typically, you will try to sit on one of the corners with just one leg supporting the front of the chair. Yet, mostly, your weight is on that one leg, since I just bring a stool, not a chair. So, Bent over and sitting makes the one leg really dig into the ground. Better is to sit a little awkwardly at first, on the edge with a stool leg under each peron leg. This helps to keep them from digging in.
2) After a half hour or so, they get uncomfortable, regardless of what way you sit. So, you move a bit to alleviete this. This makes them dig in, potentially making the stools unstable. Watch out for that.
3) The carry strap is useless. Cut it off and save a half ounce or so.
4) At 250 lbs, they are relativly light duty. I check the legs before I go around the rivet. They seem to hold up well though. So far no real cutting into the tubes or signs the rivet is loosening. About 500-700mi on them.
5) The seats are heavy duty, but, not waterproof. Knock them down and turn them over at night, else they can be cold when you sit if they are wet... They *will* hold a puddle and saturate the fabric.
Since I only take these when I am canoeing, weight is not really an issue. But for the pair, plan on an extra two pounds. For the convenience, they are worth it for not having to bend to get your shoes on, for sitting around the camp fire, and for sitting under your tarp while cooking. They also help load the pack by holding it for you and while changing cloths(sleeping cloths->day cloths); they keep things off the wet ground. At night, I turn it over and hang my socks(one leg and center) and shoes (one on each stool leg. They dry quicker/better if they are off the ground.
