1) The dimensions / price convinced me right away. In fact, I watched other reflectors at the same price but they were smaller, say 60 cm (not enough for my taste). Willing to pay the price, so take the greatest!
2) The oval format seems very convenient to me both pictures in portrait and landscape. I have not yet had the opportunity to test it but I think it can easily reflect light on two or even three people.
3) The seams appear solid (for now) but in the long view as to force the fold and unfold, they can become brittle.
4) The product was received in good condition with two plastic carrying bag and that protect the whole. The delivery was faster than expected because it was estimated between August 26 and September 11, finally received on August 20!
5) The only negative I report and is recurring on the different models I looked: the instructions for folding. Leaving the reflectors of their bag, I tried to identify how to fold but when to do it, I have not succeeded. It lacks a little diagram to explain the method. Fortunately, I found a video which helped me to fold them easily [...]).
Conclusion: I recommend this purchase for beginners and amateurs who wish to make the most beautiful portraits with a limited budget.
