Good sized working surface. The actual light adjustment touch button is a bit twitchy but the light is good and adjustable. The build quality is excellent and product styling is lovely. Good solid unit but lightweight as well. I’m sure there are cheaper light box units out there but Huion is one of the market leaders and for only saving Maybe10-15 dollars I just couldn’t take the chance. I want peace of mind if anything goes wrong that I can go to the company and have it fixed.
