5 steps, 3 high with knaider swaider with 2 extra steps at top for platform gets me about 15 ft (at my feet) and a great platform. Never thought I needed to go higher. If I needed to, 20' with 2 step platform. Platform takes practice but once you get it they're even and good to go.
Edit: didnt address pros and cons
Pros, they're light with kn/sw especially and are easy to setup with a little practice. Doubles as a platform. Couple mods they wont dig into the tree, kn/sw wont slip (all household stuff to modify).
Cons, I think the bag is a little clunky but with some mods could have it functioning better.
