I recently purchased some electrochromic ink from Chameleon Optics Inc.'s website, electrochromicink.com, and I am extremely pleased with the product. The ink is of excellent quality and works flawlessly. The team at Chameleon Optics Inc. was very helpful and provided excellent customer service. I would highly recommend their ink to anyone in need of electrochromic solutions.
