One of the reasons why I always buy my kit from a shop, in my case I use Ronnie at Factory Paintball in Stockport, so if anything goes SuperStar DJ I just go back to the shop and Ronnie sorts it and calls me a numpty.
Buying online can mean you get it a few quid cheaper but can mean more hassle trying to sort any issues out.
If you are local to Stockport drop in and have a chat with Ronnie, being such a nice man (off the field) am sure he will try to help.
