Review on 21.5 Inch Diagonal LED Monitor Anti-UV Eye Protection Filter Film With Blue Light Blocking Technology - Widescreen Frame Hanging Type by Ben Almasri

Great customer service. I registered the item upon receiving. Used for 2 weeks when a corner clip broke off during cleaning it, using only light pressure. I emailed customer service and they sent a replacement immediately at no charge. They were easy and pleasant to work with. Just make sure to register your purchase, and they will take care of any issues. Screen works well. Good clarity. I do not have the blurring the some reviews have stated. You do have to remove the film on both sides. We specifically wanted a clip on screen rather than the adhesive film, and this one works for us. Anti-glare matte finish would be a plus, but we purchased mainly for the blue light filter.
