So overall, if you are only cleaning pitches, these might be an ok bet. However, for most aid climbers, we would strongly recommend our Best Buy the Metolius 5 Step Aider or our Editors' Choice the Yates Big Wall Ladder.
You can check out our full Aider Review to see how the top aiders compared to each other.
There is a similar version of this aider made by Yates called the Yates Speed Stirrup. The Yates is a little heavier and the buckle has its pros and cons. We lean more toward the Metolius version but both are pretty comparable.
