Welcome Mame :seeya:,
There is a 45 day return for both the Classic and PalmControl AirGravers. This gives a trial time to make sure people are happy with the tools.
There was a CLA show earlier this year not far from you in Lexington Kentucky where the tools were demoed.

Do you have photos of some of your etching you can post and tell about your work?
Thanks again for joining and welcome.
