13 ft. Aluminum World's Greatest Multi-Position Ladder with 300 lb. Load Capacity is rated 4.5 out of 5 by 11.
Rated 5 out of 5 by from Great flexibility for a variety of uses... Great flexibility for a variety of uses

Rated 5 out of 5 by from Great ladder I've used this ladder fuly extended for exterior home repirs and it is strong, with no flexing or lateral motion. The mechanism by which the ladder is folded or extended is easy to use and locks the extended sections rigidly into place. Standing 12 feet above ground level I feel completely secure on this ladder - more than I can say for other ladders I've used. When fully folded, the ladder is 44 inches high and stand freely on its own feet without any support - a nice bonus which simplifies storage problems. For general household use, this is the best ladder I've ever used.

Rated 3 out of 5 by from Well, it worked We bought this ladder so that we could put up paintings in a stair well. I could think of no other way to get a ladder that would work on the stairs. In that sense, we had to have it, and it worked. HOWEVER, it is very difficult to change the angle of this ladder. I'm a pretty strong guy, but it took me and me wife, using our full force, to depress the buttons that allow you to fold up the ladder. And if you're trying to fold it up, using all your force, and suddenly it releases and closes, there's a high danger that you can seriously pinch your hands or fingers.

Rated 3 out of 5 by from Could be higher quality Received product in a timely manor. Soon as i opened the box I found one of the step adjuster rivets had been broken off and the little plastic cover was no there. This holds in the pull stop for extending the ladder which there are 4 of them. I needed to use the ladder right away so i went ahead and fixed the adjuster and added a new rivet next to the old hole. I found that the rivet end only sits in a approx 3/16 inch indentation within the plastic that stops the adjuster from sliding out. To me the adjuster stabilization being cheap plastic is not of good quality. I am sure that because I had to fix it that my warranty is probably no longer good. I don't know.

Rated 4 out of 5 by from I love this little ladder A very good ladder. It adjusts easily and is great for working on the stairs. I appreciate that it fits in my car and that the steps are wider than other ladders so my feet fit without getting sore.

Rated 5 out of 5 by from Does what it says Heavy but versatile. Definitely read instructions not just watch youtube video demo.

Rated 4 out of 5 by from Very Close To The Little Giant Was very happy to see it come to my home address fully assembled and ready to use right out of the box. It is lightweight and easy to use. Reach is 13 feet with the use of my arms at a safe place on the ladder. I was able to use on my home as soon as I got mine.
