I have used this model for two years. It is extremely light and compact: if mobility is your objective, you can't beat this model. It is not very comfortable: even after adding a closed cell foam pad to the original seat pad, 3-4 hours is all that I can take.

I do not climb in the recommended way (hold seat with forearms and lift platform with legs): this is way too gymnastic. Instead, I balance on the seat and pull up the platform with the two connecting straps. This works very well on smooth bark trees; not so well on rough bark trees like cherry. Descending is similar except that I added a wire loop on the end of the platform so that I can tip it up with my foot to dislodge from the tree.

I will probably purchase the sit-n-climb seat to use with my platform. I suspect this will work out better. In hindsight, I wish that I had spent the extra few dollars to purchase this version at the beginning.

I have also looked at the Summit Bullet backpacker, but I think that I prefer the Lone Wolf.
