This little sandblaster has no dust collection, so you'll need to add a filtered hose or collection box to the back or it'll cover your workstation with sand within seconds.Emptying/reusing spent media is kind of a pain, but the whole box is so small and lightweight that you can just pick it up and dump everything out to re-collect it.You absolutely need to invest in some replaceable screen protectors so you don't etch the window and lose visibility.The only thing the power cable powers is the light. The foot pedal is just an analog air valve, not a solenoid, so when you release the pedal, media continues blowing for a couple of seconds. If that isn't a dealbreaker for you, this system is absolutely worth it. Paid for itself with one project.
