I really like this product but it could be so much better. For one thing the metal strip is only on the cm/mm side I don't use these put it on both sides Please. Its very long can be good and bad depending.. For the most part it works great! They just need to put the metal on Both sides.
I have used this tool a few times on a project and love it. I like how it has a metal edge on one side so I can use my craft knife. Also, it doesn't move around like most rulers do because I'm able to hold it down from the top and my my cuts have been straight.
