Door top runner kits

[JohnR2]

Has anyone tried the Stamp Panel runner kits on Ebay at £25 each set? Is this the same as SP4X4? they're both Liverpool based. i wondered what the quality is like?

I have some, they came with the galv SP door tops.
Whilst I can't pass comment on their accuracy Vs an OEM set, I can say they fit and function perfectly well, slide with a pleasing amount of resistance and don't let the rain in.
I'd defo have another set if I needed some again.
