Not a whole lot to say about these. They are cheap and they work. Simple as that.
Got them with a leapers accushot 3-12x44 compact for use on my AirArms tx200. To get the right eye relief on the compact scope i had to not use the locking screw that goes from the ring into the breech of the airgun.
Was a bit worried the scope would shift due to the rather heavy vibration from the tx200's spring with only the 4 tightening screws holding it on, but after 5-600 shots it is still exactly where it's supposed to be.
Pros: solid, cheap
Cons: Can't really think of any.
