I read a while ago on the The window cleaning warehouse site that the Wagtail rubber was now black and not the orangy red colour it first was. After that I bought a 6 inch flipper which arrived with a black rubber, this rubber is amazing  except for the fact i dont use it much as i only need it occassionly . anyway I decided to order some more from the warehouse and when it gurned up it was that orangy  dung which imo is horrible rubber . I phoned up the warehouse and they say that the rubbers are black or  orangy/red but the difference between the rubbers is outstanding, they are different . I was just wondering if they were getting rid of the red stuff they had in stock, any thoughts , cheers

I found the red and black wagtail rubber equally dung, they were both removed and binned after trying them on one window

The Wagtail red was tested & found to be superior to all rubbers on the market. However, I wouldn't use it in cold weather - perhaps now is the time in the UK to retry it? I heard it was warm?
