I've been dealing with this company for about 3 years. My previous experiences with this company have resulted in me returning my battery and light on different occasions because of either the battery or the light stopped working for whatever reason. I've lost count as to how many times I've sent my products in to be serviced. At one point, I actually ripped my light cord in half due to frustration but they were nice enough to discount my replacement light, which costed ~$125. Their customer service reps are generally indifferent to your experience, and I really think these loupes are made in a garage.
Long story short, stick with the brand associated with your loupes.
