I needed to replace my smoke alarm, which is located on a sloped ceiling, about 13 feet up. My trusty extension ladder was moving and flexing a lot and was scary to use. I guess I outgrew its weight rating somehow (200 lbs).
So I've been looking at these Little Giant Ladders for a long time, after seeing them at home shows. The LT looked like the best ladder for me since it is fairly light (38 lbs), and is rated for 300 lbs. It would give me a stepladder as well as an extension ladder.
The stepladder mode at the max setting couldn't quite allow me to reach the smoke alarm, but the extension ladder at the minimum setting did the job. I was able to climb up safely and confidently to replace the smoke alarm, including hardwiring it to the AC power.
I had no trouble moving it around, including going up and down stairs. The Leveler model that Lowes carries is about 5 lbs heavier, and I didn't want to get one that heavy for what I expect to do.
