Sturdy, strong, safe. I am 240 and have been using this with a 24ft ladder to reach the second story roof. I don't know what I was thinking using the ladder before without this thing. I could tell a huge difference between using the ladder without the stabilizer and with. Works as advertised on corners also. The pads do fall off from time to time when I move the ladder around but nothing a touch of super glue won't fix.
