The original Quanum FPV video visor got my thumbs-up as an offering which represents great value but it wasn't without its weaknesses. HobbyKing have addressed some of those complaints with the addition of the "pro" upgrade neoprene glove and the V2 add-on kit.
Both these options improve the basic V2 visor in different ways and may be worth considering if you've already got a V2.
The new lenses do produce a sharper picture but, as many people did with the original lenses, you really need to move the LCD screen to the outside of the EPS frame in order to get a comfortable focus.
By combining the 1.25x and 1.5x lenses this visor now provides a very comfortable FPV viewing experience.
There is some duplication between the pro glove and the add-on kit and I found that after the build I had lots of cables and stuff left over so it might be nice if HK broke out the components and made them available separately so as to avoid waste and reduce cost.
Disclosure: The "pro" glove and V2 add-on kit were provided for review by HobbyKing.
