The product is good work and for the price is also unbeatable. Only the description is a disaster. I have no problem with English descriptions, I'm good English (my degree is in English and I never had problems understanding). But the English description is Chinese-English. Sentences that one understands the third time still not read. That's just for someone who for the first time has a wireless remote shutter release in his hand and actually do not know how that works not so great.
