I bought from Towsure a Towbar Socket 7-pin N-type (SKU: S5). I also purchased a Towbar Socket Gasket (SKU: S82) and a set of Towbar Socket Mounting Bolts (SKU: B68). All parts were received, but then found that the socket and gasket were not as pictured and the gasket was therefore the wrong shape for the socket. In addition the socket mounting bolts were far too short to extend through the socket, or any other socket I have seen. It looks like someone at Towsure might have realised this as they had crossed through the SKU on the packet. Unfortunately some other individual is still sending them out. I have contacted Towsure twice politely asking for their advice on these issues, but a wall of silence. Very poor quality of service and parts. Not to be trusted.
