I would offer this is the only company I will do business with regarding Class 4 Laser safety. Their service is second to none. Regarding the acrylic face shield only, and its protection, this is absolute. The hardware metal screws are of a poor grade and sheared in half. The controls to elevate the face shield, will not properly hold the face shield elevated, and all plastic components, excepting the acrylic face shield, component plastic used, is some sort of possible styrene and not acceptable for this application . I wear their CE protective goggles in the 445 NM in the event the unit fails, and if you do, the face shield has merit in Class 4.
Quick and responsive service as well as a superior quality product.
Excelente cumplimiento con la entrega
Expect excellent service and certifications sent on each pair of specific lenses to the end user client. You cannot get a second chance with high intensity lasers and your eyes. I absolutely trust this firms product, their certifications and their excellent service.
