Purchased just now for my live-streaming work. My opinion after a quick usage :-
+ve: 1. Very good performance, just like the multiple positive reviews on YouTube and Amazon etc. 2. No installation required - simply plug and play. Gets detected like a webcam. Very sleek and small. 3. Packaging and delivery were very good. A useful USB extender is also provided. 4. It works perfectly on my i7 laptop. Doesn't show any lag on other i3 device even though the recommended config is i5. 5. Almost no lag or delay.
-ve: 1. The device gets heated very quickly. I don't think it would be safe to use it outside an air conditioned place. The heating issue serious - it is not mild heating but a potentially device-damaging level! 2. With no warranty, it looks like a risky investment. 3. Expensive - got it for Rs. 12,748.00 (but you don't have better alternatives)
Will update the review after using it for a couple of months.
