Hehehe.
The Nano point is their top of the line model. It's a reflex heads up display sight. It costs about $120-130 bucks. The one i have is the PS-55, it was like $90.00. The PS-55 is the perfect height for an AR flat top rail.
Mine has been (deliberately) turned on to the best indoor setting (power level 2 of 7) for 3 weeks straight. So far the reticle is completely visible and seems unchanged in brightness. I plan to leave it on continuously until the day i decide it's too dim to be useful at that setting....just to see how long the battery will last if SHTF.
When i shot it at the range i was able to adjust point of aim to the exact center of the 5 MOA reticle at 25 meters with XM193 ammo. It shoots about 1/3" groups at that range with Federal XM193 ball. That ain't bad at all for a 16" carbine with NATO ammo. The match grade trigger really helps to shoot little groups.
If you can only afford one or the other
get a trigger.
I have a Chip McCormick match grade drop in unit.
Oh....yeah....NICE SPOON!
