I just noticed this post so I realize it's a little late to respond. CFST are deathtraps in IMHO. The steps are short in length and VERY easy for you to slip off. The steel pin bends w/ any kind of side pressure. I've been using Cranford screw ins for over 20 years. Nothing beats them. Hold one of each side by side and you can see the difference. I still have few and every once in a while, 1 ends up in my bag. I make sure it's one of my bottom steps. They make me feel uncomfortable when standing on one at any kind of height. That's just my opinion. Others may feel different but you really can see the difference when both in you're hand at the same time. Cranfords are a much better product and worth the extra $.
