Opticstar imaging filters?

Hi all, Just stumbled across these imaging filters on the opticstar

website(shop in Manchester) http://www.opticstar.com/Run/Astronomy/Astro-Accessories-Imagers-Opticstar.asp?p=0_10_5_0_3_125

They seem very very cheap - Has any body had any experience of them before?

Cheers in advance.

I had a set and used them for my planetary images with my mono DMK. They're a good starter set of filters, based on Kodak wrattan plastic filter material. I now have a set of Baader glass filters for my ccd camera.
