Its a tricky one, they are a daft price. But what price do you put on protecting a good scope?

That said, i believe Butlers are second rate.

Poor Fitting.
Rubbish spring action.

Not actually waterproof either, when the highest point of the scope is a knurled / notched ring, such as a fast focus occular - moisture just runs through the low points.

Have had more success with Bushwhacker tbh. Dont look as good, but actually work better.
