I take a lot of portraits and small sports shots outdoors under the hot sun. It helps control the light. This allows me to light the subject more evenly without harsh shadows.
The 50 inch reflector is great, the materials seem to hold up well over time, I like all in one style and it's big enough for a single person, a Couple or small person group, big and indoors!
I've only used this tool a few dozen times since I bought it in February 2015, but I mostly shoot landscapes. The only problem is that the loop I use to hang my bag on the hook is worn out. I have purchased Westcott umbrellas and the quality of these items and the 50" size is the reason I ordered this product. No regret.
