Are they built to last? I often read people say they "practically have it running 24/7" so I'm thinking I have nothing to worry about?
The thought crossed my mind as I cut something like this:

the end result was BEAUTIFUL, but yeah, the knife is constantly going down to make an invisible cut, repeat a couple hundred times. up down up down up down.
If I can do something like this, leave it on for a while and come back and hope to be able to do that for a year that would be great. Thanks everyone.
Edit: I guess one way to rephrase my question is: how much do you use your gx24 and how long have you had it?
