ITG Filter for Cup

[Cuppy 172]

Ordered my new panel replacement filter from ITG on Friday, the guy said it would take 2 weeks to be delivered. He also said it was not a stock item as it needed to especially made for the Cup?

Any body else got one of these filters, any difference in responce etc?
