The company, Ecologic Mart Service, sent an email the day after I received their product, outlining some of the highlights of their product. This is excellent customer service! I use the light for night reading and loved it! Time will tell about the ongoing quality, but I feel the company will stand behind its product should anything happen. The quality of the product was excellent too! Easy to use, 3 settings for brightness, which is great; overall, the product gets a 5 star for easy to use, quality, and durability.
