Review on Lincoln Electric K4134-1 Auto-Darkening Welding Helmet by Sean Bouchard

Defective product. Revain cannot be contacted for a refund. I could have been seriously injured. The auto dimming function does not work properly out of the box. Do not buy this product or contact Amazon. I've been waiting for an item that may have seriously damaged my vision for over a week. I need to order from a reputable source. Will not do business with Amazon or Lincoln again because of this.
