A mate who was a subscriber gave me a code for 1 month free trial. Jordans' Rangers articles are all excellent, well written and researched, and go into loads of detail. He seems to have good contacts/access within the club. They offer proper analysis rather than the rubbish sensationalist click bait the MSM offer up.
At the end of the trial, I didn't subscribe straight away but then got offered a half price offer subscription (£30 instead of £60) and went for it.
I would say it's well worth it for the Rangers articles alone, however if you also have interest in other clubs, the Premiership, Bundesliga, Serie A and La Liga then I find those articles excellent too. You come away from every article having learned something.
Another small point is they offer the Totally Football Show and Zonal Marking podcasts without any adverts. I listened to those before anyway but always had to fast forward the ads so its a small bonus.
