Review on Effortless Precision: SimpleMarker T Square Marker for Woodworking Perfection by Anthony Lopez

This marking tool concept was great. But after checking again with some tape measures and vernier calipers, it's off 1/16 inch from the curved part of the tool. This means that to mark on a 1 inch line you actually have to use 1 inch and 1/16 inch marks. The font could have been bigger (god knows there's room for a bigger font). All in all very disappointed with the tool. A few subtle adjustments in its production could have resulted in a neat little marker. Instead, it's almost useless due to lack of precision and tiny letters. waste of money.
