I have used this product for three weeks so far traveling from Michigan to Alaska. During an overland trip of this distance having a quality product that you can depend on is extremely important. I was extremely satisfied with the case and charging system, granted the light lasts for a long time but while testing the case charging option out I had charged the light with two full charges and had power for more if needed. I think this is an outstanding product and will recommend it to our clients that visit the lodge this summer.
