I have not used this yet. The quality looks good though.
I'm very happy with mine, really great quality. However an idea for improvement would be for a lenghtier pole to allow using it for up to around 20 cm (around 8 inches) instead of the actual shorter length.
Only improvement I would make is a list of tips and uses or just links to YouTube channel
This is a great marking gauge. The micro adjust makes a huge difference.
Works as advertised. Well made.
