An easy well to tell the Noob from the H, is the indices dots. Or the lume application on them. The Noob is much less domed, and more like the Gen's. While the "H" lume is very convex, or half domed and way too tall.
Bugs the dickens out of me! Grrrrr!!! :-(
The Noob is much less high domed, and much closer to Gen.
