I'm working on my Apartment Balcony as i Don't won't my birds get ill cause to the dust particles or smoke, obviously i live in the lower floor of the building the smoke would rise to the top of the building and my neighbors would get disturbed so i was forced to by a smoke extractor, after many researches and youtube videos i decided to buy Vevor 100w fume extractor (obviously with doubts) i would say as a new laser engraver i have to spend less to build up my work space until i start earning so this was the most intelligent choice i have done and i'm so happy about the purchase and also of the fast customer service.
