Perhaps it is my false expectation that causes my poor review of this product. With that said, the PST comes with protective covers and that is a good thing. The rub comes if you install the KillFlash, you can't use them (OD problem). I get the logic but the practicality escapes me. In and of itself the KF is great. Its simple to mount and does not blur or otherwise interfere with the optics.
Pros: Easy to mount
Cons: Covers don't fit
