Focus on the cons, the pros are too many to name and this is the clear choice for a little red dot. You'll never convince me to buy a $500 red dot for my 22 because I don't need 500m clarity to shoot 150m.
Pros: Affordable, doesn't obscure anything, mounts low
Cons: Slight fisheye, have to dismount and re-zero to replace battery
