This photo perfectly illustrates my only complaint with my NR360 (and somehow, though I bought it new 3 weeks ago, it says "ver.1" in the manual and has the clear wrap-over dome with the more visible air vent on the front side (which I prefer anyway..)). My complaint is with the unit's candler, where the plastic housing is too translucent, glowing brighter in use than the eggs we're trying to examine. It also lacks sufficient intensity to illuminate my Ameraucana blue eggs, even after I brushed a 2" wide band of black nail polish around the candling port.
Otherwise, I couldn't be happier with my NR360!
I have seen people put black tap around it so there isn't any bleed through of light. I don't actually use the built in candler because I like my high lumen flashlights so I can see better I guess, lol.
You have the newest version. Its NU1 correct? The dome is the newest.
