Ok. So this product after I purchased, didn't give me a genuine product tag from Boya. Unlike all other boya lapel boxes, this one has a colorful QR code. Is this legit? I tried scanning and putting the Security code in Boya Site itself. It said no data found. Tried many times. I then also tried to check the product by putting a lr44 battery which I had. And used it on my DSLR input. It was only noise captured. My voice went totally missing. I checked that the switch was towards 'Cameras' only. The box also had a pricing sticker behind which said, 1650. Genuine boxes don't put such things. I never got a genuine feel at all thought the product make looks as same as what it should be. There was a boya logo on product too which was strange & at a wrong place. I straight away returned the product the next day itself. Maybe I got a duplicate product than what others may not have. Check well after you buy it.
