My sister's boyfriend did it, but it's pretty straightforward I believe. You have an app for your smartphone that controls it. We have the twin pack with two nodes that serves our house fine, can even get a signal at the top of my garden
It's nothing new though mate. Look before every major tournament we've played in in the last two decades..... always some controversy and the press blow it up to our detriment
I'm not even mad at him getting the tattoo though, the meaning etc etc that's his prerogative, just wish he could've done it after the WC. We know how our pathetic press love to fuck us up before major tournaments
