Some sort of rack and pinion setup with a measuring scale might be useful. Otherwise it would take longer to dial the right offset in than it would take to do a dozen cuts with a track saw. You'd still have a giant bar sticking out of your saw waiting to get bent or scratch stuff.
As an Industrial designer . I would have made the base plate adjustable by allowing the user to adjust the required length to suit their circular saw. Some one didn’t do their target marketing properly. As NO one would purchase a silly contraption to make their saw impractical to use.
The point of this thing is to sell it to hopeful/stupid people who just need more practice. A beginner who thinks they just can't get a consistent cut, might grab this thinking it it is the cure to all their problems.
I have one, use it all the time, I like it, I use it for things I would’ve needed a table saw for (mostly ripping osb), it’s not quite as precise, but a lot lighter, cheaper, doesn’t take up a ton of space in the trailer, is safer to use, faster for what I’m using it for, and requires less moving around the sheets, making it more efficient.
