Bought a reflink at my last visit to twickenham and was hoping it would work when i go again at the end of the month?

I wouldn't have thought so as the devices you use are specifically created to monitor a certain frequency which you cannot change unless you tinker/modify it, and they alternate/change the frequency each game, I've bought a few and since they go for around ￡5 each game you would've thought they would be re-useable! It's worth a try atleast, but I wouldn't get your hopes up :(
