I needed something for the intricate small projects I do. I enjoy thread painting embroidery which requires good magnification and lighting. The Brightech model is perfect. The base is very sturdy and the wheels move easily. A very important element for me as an artist was being able to adjust the warm and cool colors. It just seems like every detail has been carefully thought out, from the protective cover over the magnifying glass to protect and prevent dust to the position of the arms. I am so thrilled!
