Good products that work and are recommended by experts in the field; I use them myself and recommend them to my patients. However, it’s disappointing that the company doesn’t provide any customer support or respond to emails or inquiries, although I’ve tried more than once. And the quality of some of the products is lacking: the screen filters aren’t upgraded to fit newer models of computers and other devices and so I’m left trying to adjust an old oversized filter so that it doesn’t block the camera. And the black material on the frames of my blue blocking fitover glasses is flaking!
