cost me around £120 for the e link and software. railmaster turned out to be a evaluation copy and i had to then pay a further £69 for the full program. railmaster was terrible never worked properly spent more time unplugging usb,s and plugging them back in then i used the program itself. asked for a refund which railmaster agreed. seems like railmaster are so uncapable that i have been now waiting over 10 days and no sign of a refund. no wonder their software is rubbish if they can,t even manage that. now they are ignoring my e mails. problem is that e mail is the only way of contacting them. so i feel that i have been ripped off terrible customer service
