Ottawa, it shoots better than any other open sights I've tried, at least for my eyes.
Rb, it does have a frown face! Lol! The eyes are reflected lights in my shop & the mouth is the edge of the solder. I need to paint it with flat black. As far as precision goes, it's crude, still quite blurred , but with as many years shooting as I have I'm not bad at aiming "by guess & by golly"!
DWS, it looks quite crisp in low light, but seems to blur substantially in sunlight. As I said, it's the best I've tried yet for my eyes. I much prefer aperture sights like on my 45 Sharps, but the purists here won't let you shoot with anything but hysterically correct, open sights.
