Snap.
I fell for it out of curiosity but I did think for the small cost it may have been worth it but it wasn't.
I also bought a pile of duff rubbers advertised on eBay for 10 quid or something similar only to find the whole lot were naff. They were supposedly made by Dunlop but they had no trade stamp on them and were all off cuts of different lengths not the 20 or so metres advertised.
The whole lot were useless.
Yes, I know, don't tell me ...... there's one born every minute ......
