Best thing ever, in the history of ever ness!
I love this construction masker calculator!I purchase a lot through amazon, this is, with out question my best purchase to date!There are tons of great videos out there to show you how to use, and how to customise!The main reason I like this particular model, is down to the fact I can use it in Metric. Being in the uk we use both matrix and imperial, this is so versatile I can use it interchangeably.A must have!!!!
