I was eager to give LUMINTOP a try as a consumer in search of high-quality, low-cost products to enhance my life. My own personal experience, though, was not unique. The handheld flashlight I bought had a short battery life and was erratic in its illumination. I tried to get in touch with customer service, but I only got unhelpful and condescending responses. A corporation with such potential should do better than to fall short in both product quality and customer service. I am unable to endorse LUMINTOP.
