Thanks, and they are Asda's exercise bands they come in a pack with three strengths (and colours) and are £6 a pack or two for £10. There are a few reviews on you tube and are apparently as good if not better than theraband !
I havent used catapults long so the guys on here may be able to confirm that, but they appear to be ok. I made the mistake of buying a cheap cutter so struggled to get a clean cut, Ive now bought a better one and the band is cutting nice.
