I recieved my dixie air horns on time but after paying to have them professionally fitted because there was no wiring instructions with them they played La Cucharacha. I e-mailed the company and they sent me another set which also played La Cucharacha!!! I then Contacted the company again asking them to please send me dixie horns and to check that they were actually Dixie air horns. They arrived this morning and guess what, they played La Cucharacha. I am now totally fed up with this whole business and am going to demand my money back. I would advise anybody thinking of buying from this company not to. In my opinion they are totally incompetent and shouldnt be trading.
