Ok, looks interesting, but not much information--a new product. It doesn't seem like it will work on a sliding miter.
My solution helps a lot. I set up a U shaped structure above the saw and hung a clear shower curtain around the saw. There is just enough room for the saw to swing without impeding the slider bars. The shower curtain hangs down to the height of the saw motor and comes around the sides so that the majority of sawdust winds up back in the curtain. The curtain is gathered into a box with a 4 inch dust port. The top of the curtain is covered as well. I used aluminum duct tape to hold it together, which holds far better than I'd hoped.
As I used this, I discovered that cutting technique has a LOT to do with sawdust dispersion. To minimize that, I now make a very light cut across the top of the workpiece, then push the blade back and down. The first cut forms a channel that throws most sawdust back into the curtain.
Dramatically cuts flying sawdust. Next step is to take a small piece of aluminum and curve it into a U shape that fits on the built in 2.5 inch dust port. I'll affix the U shape just behind the fence so the sawdust will be directed into the port. Ample suction will catch allmost all sawdust coming off the saw.
This is constructed against a wall and I used two large L brackets to hang the curtain. Measured the width of the saw with it at both 45 degree settings. The table is on casters so I can pull it out a little for 90 degree cuts. I screwed a stop bar onto the floor to push the table back into storage position.
Sorry no detail. I had but can't locate a picture of this setup. Took an hour or so to put it together. There are many ways to do something like this, but this was an easy fix, and cheap too.
The more I do, the less I accomplish.
