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.
Dance like no one is watching.
Sing like no one can hear.
Scratch yourself like you think the zoom meeting has ended.
