The Webcam is pretty nice. I don't know if it is like a Logitech C920 but its very satisfactory. The cost x benefits worth it. I recommend. The seller just delayed a little to send but it arrived on Brazil with 9 working days.
I bought it for autofocus feature. When I saw a blitzwolf brand, I thought it was good quality. It arrived at the smooth address with the cargo company 7 days before the expected date. I bought it in taxes. No broken dents in the air bag. The PC is connected only with the USB cable. Win10 saw automatically. Standard camera recognized it. Full HD takes pictures and videos. Autofocus really exists, it's like it's following the face. Do not expect an ayfon11 quality. Lightly sandy in low light. The desktop fits well on the monitor, it's up and down. Good for Zoom. Amazon everyone gave 5 stars, the clarity in the evening wasn't so great, but it wouldn't be breaking points. I don't have a logitech comparison.
