Not good so far
I purchased this and was initially impressed with this sight. Then I tried to zero it in, no luck. Closer inspection revealed the front lens was crooked in the sight. I am waiting to hear back from Holosun and will edit my review when/if this gets resolved.

Excellent sight for the money
Love the reticle. Easy to find on a handgun.

Best Holosun for the money.
Worked way better than I thought. Just ran it through a fighting rifle class and it works great even in the rain. Can’t beat it!
