I’m actually beyond impressed with this device. After unpacking and a quick 20-minute charge, it was ready for use. It looks large but I’m so impressed with how light it is. I didn’t even notice it around my neck. The “ arms” are totally adjustable and move in your direction choice with no effort. The light brightness levels are distinctly different brightness levels and really do offer great light for reading, looking in small dark spaces and Etc. I have used it now 3 hours on and off and have as yet not needed to charge it. Customer service was also impeccable. 5 stars all round
