I have several StellaPro lights. I was looking for something that provided flash with a fast and reliable recycle times, without overheating. I do macro focus stacking and some of my images can be over 1,000 images. Anne, helped me understand the difference between the different models and accessories, then sent them to me very quickly. Once received, I was very pleased with the versatility, ease of use and solid design and build. A little in the pricey side, but I find it’s worth the money. If they were a bit cheaper, I would buy 3 more to replace some of my other lighting. Gets my strong recommendation.
