I have a townhouse that I bought as a rental property. For some strange reason I decided not to let go of the 1000 dollars in labor to have it painted. So, instead I invested in this ladder. I needed a way to paint the stairwell and this ladder worked perfectly. It is a little heavy for this old man, but I can move it up and down the stairs. I can adjust it without help and was confident up high in the stair well.It can be taken apart and used as props for scaffolding or as two step ladders. I have not used it as such, nor as an extension ladder.For a ladder it is complicated, I had to read the instructions, but as a versatile ladder it was very good.As usual, it came on time and in good order.
