Overall the guard is built extremely solid, is easy to setup and improves dust control on my saw.
I would have given 5 stars however there are 2 small items which I believe need to be addresssed. The mounting kit provided to use on the Harvey Table Saw is solid, however if you choose to use their Spider Mobile Base you would have to retract the support foot each time you wanted to move your saw. I fabricated a bracket to bridge the support leg to the top of the Mobile Base. It would be great if a bracket for that option existed.
Another small issue is the main horizontal tube if you're using a 36" Saw setup. I ended up shortening the tube by roughly 12" because it stuck out way too much to the side. An option for the 36" setup would be good.
