Works great for me.
I've been using this marker for a couple of years. It's small, lightweight, and handy. I like the fact that I can position it and draw two pencil lines at the same time; the angled line on the face, and the 90-degree line on the end grain.
Simple, clever, accurate
Useful whether you are new to dovetailing or are a prolific pro. Two advantages over the standard adjustable bevel gauge. First, the angle is accurate and consistent, not subject to accidental bump or creep. Second, and more important to me, it acts as a saddle square guaranteeing the angled face mark is aligned with the 90 degree edge mark. I was concerned that it's made of wood (there are excellent aluminum ones out there) but now that I use it I'm pretty confident the only way I'd break it is to step on it (grimace). If you only use one angle, consider an aluminum one. But this T saddle is a clever design that gets you two different angles while still letting you flip it for the left and right marks.
