I purchased this product last week Because I was looking for a portable sofbox. At the first set-up one of the mounting rods of fiberglass which immediately broken, I Replaced it with one of the 2 spare rods in the package. The next day I left the softbox open (mounted) without using it and at the end of the day 2 other rods were broken without anyone touching them !!. A bad article! The rods in fiberglass are so fragile thatthey simply can not stand the tension ... Nothing to compare with similar products with rods in harmonic steel. The rest of the softbox is plastic Which leaves no doubt ... cheap despite of its price. For this article is not possible to use the word "professional". I asked immediately for the return of the item and refund. I do not advice it at all.
