When first used it was difficult to open but has gotten better with use. This ladder is designed as a 10.5 foot step ladder as well as a 21 foot extension ladder. it is acceptable as a step ladder, but, it is too heavy to use as an extension ladder. Once extended to 16 - 21 feet an average person cannot lift it up against a wall or tree. I thought it would be more versatile than it really is. Definitely not the worlds greatest!

Rated 5 out of 5 by from Great ladder Great ladder. It's a bit heavy if you have all sections together, but manageable. Also, if using it as a full extension ladder, difficult to raise up to full height, but being over 6'4" not a big deal for me. Very versatile, including step ladder, extension ladder, stair ladder and scaffolding. Given the choice between a full size step ladder, an extension ladder and a set of small scaffolding, or this ladder, I would pick this ladder every time.
