I've used them and they're fine. They did have gorrilla's 3 yrs ago, the baby kong,which is a quality product. These comfort zone ones are not as good mainly in the seat comfort. I've hung one up and they are solid once hung. The model I have this year does not fold up for easy carrying,or you need to attach the last two bolts on site. Doesn't really matter to me since I can drive my truck to within 50yds of the stand site.
