I immediately bestelllt more Dot-it's for the new camper. Without first having to lay a power line, light is where it is needed. For example, in the gas box and wardrobe. Power really nice light. Have those Dot-it's been since 2005 regularly in use, and they still work (with the first battery) in spite of weather conditions vary (from +40 to -10 degrees). From my perspective: Highly recommended.
