I forgot two. I have a Japanese made Tasco that the crosshairs went sideways on. Also have a Leupold Scout scope that probably needs work. The rifle quit shooting. I took the scope off to work up cast bullet loads for a match. Then I shot some jacketed which shot well with a receiver sight. Put the Scout scope back on and it patterns. Need to check it further but it doesn't look good.

I also had to send the Leupold 3-9 Compact back twice because there was a piece of dirt floating around in the view.
