I bought it straight away after seeing a video of it in action. My opinion, I thought it was fun to use considering its a lock on, it's got 450m range which is nice and the velocity type is a cool gimmick. It currently has a reload bug with only reloading 1 rocket a time from a ammo pack. Like with other lockons I think their effectiveness against air will diminish as pilots learn to jink the missiles. Over all, I like using it, I don't like it so much when used against me.
