In the EU everything electrical comes with a two year warranty. I bought an MSF receiver module on eBay. It arrived from overseas and it took me a couple of weeks to get around to testing it when I realised it did not work.
I opened a PayPal dispute and they closed it because it had been longer than 45 days since I bought it. Some stuff takes nearly that long just to arrive from China! As usual PayPal are cocks.
I left the seller negative feedback because he refused to accept a return. I asked Santander about a charge-back but they refused too, the asshats.
