We purchased this product from an Industrial and Scientific retailer and are thrilled with the results. Based on our own experience, this adjustable holder bracket is perfect for our needs as it fits a wide variety of lighting components and ensures they are held securely in place .The pros of this product include its flexibility and durability. however, there is one con we found- it may take some time to adjust the bracket to fit the desired lighting component. Overall, we highly recommend this bracket to all those in need of a reliable and flexible lighting component holder..
