I have had mine for going on about 6 months.
It has been used on both a .223 and a .308, and so far no problems. It zeroed on both rifles, and held zero with round counts so far up to about 500.
Based on my experience so far:
PROS
Price
Multiple reticle patterns user can select with switch
Ability to turn it on and off, and adjust brightness with switch
CONS
Size / Weight
Does not have the track record of the JPoint or Docter
I bought mine because I wanted to see how I liked a miniature red dot backup in combination with my scopes, but I did not want to spend $200-$300 on the JPoint or Docter to find out that I did not like it.
So far, I like it a lot!
At this point, I am going to keep using it until it gives me trouble. If it craps out or gives me trouble I will replace it with a JPoint or Docter.
At this point I would say it is OK on the firing range, but I would not put it on a rifle that will be used for Law Enforcement or Military application.
Hope this helps, if you have anymore questions let me know.
Good Luck,
