They are great if you love crosshairs that move. The sweet series has a very bad reputation. BSA tried to pack to much into a low cost package.
I got one, the Sweet 17, lost zero after about 3 shots, no it was not my rings or mounts, they did not change from my previous scope, and I checked them multiple times. Sent it back to BSA, got another, did the same, sent it back, got another, DID THE SAME. Sent it back, got another and sold it then purchased a good scope. The only scope I ever had that was worse was a simmons 8 point.
There is low cost, then there is cheap. Bushnell Banner is far superior in lens quality and reliability rating, Simmons white tail classic is another that is good.
