Must-have, but beware the small print for fitting!
When you are recording at a desk, it is vitally important that you stabilise the mike you are using so that any vibrations from keyboard, mouse etc don't shake the mike and send random sounds/bumps/rumbles etc down into your recording. The best way to stabilise a mike is using a shock mount, or, as it should better be called "an anti shock mount!"
I purchased this particular accessory to use with the RODE PROCASTER ... it fits well, removes all vibration I could throw at it, and generally performs as it was designed. I purchased this particular model as it had an attached pop filter, something I needed. However, it transpires that the ProCaster is longer than other Rode mikes, and therefore the inbuilt pop-filter wont actually reach where its needed and is thus quite useless for me anyway. I was going to return it but it would cost me more in return postage so I've just snipped the it I dont want off ... the shock frame is the main thing and I'm happy with that.
So, great product, but be very careful to ensure that it fits the mike you are buying perfectly!
