Use it as spot mics on hihat, snare and ride.
It is useable on OH as well, but off course the resolution is not up there with the best. But for the price you will not find anything better. And as spot mics, where top resolution is not required, they are really useful!
As OH they lack depth and perspective. Really cheap and batter for OH are t.bone SC-140 (you won't find anything better in the price range, believe me I tried!).
