I gave this scope an extra star allowing for the very low price. Other than that it's pretty so-so. It is quite clear and the cross hairs seem to track correctly. I needed almost all the eye piece adjustment to get a focus at 50 yards and the parallax ring feels a little rough as it moves. I cannot speak to the strength of its construction. I'm using it on a .22 rimfire for small varmints around the property so there is nothing at risk if it suddenly malfunctions.
