I've own a few Photoflex produces over the years. They are very good when new, but I've learned that the less expensive materials they use to manufacture their produces degrades with time. Ultimately I've had to replace all the Photoflex stuff with better made (more expensive) produces made by other companies. In the long term it is usually cheaper to buy the more expensive products. I don't mean "gold plated" produces, just look at stuff that is one or two price points higher.
