My wife got it for me just the other day. I haven't tried it...I still use my regular grates as well as my cast iron ones. I'm excited to try it. It was only like $4 bucks...How can you go wrong. You could use it on your smoker.
I needed some tool holders so I bought two of the Weber ones and just straightened them out. I smashed the tabs flat with a vice grip then I drilled a hole and screwed them to the railings. Then I went and bought some of those leather rawhide shoelaces. I made loops on most of my tools. It works good for me. Now I just need to get another!
