I blew up my bike headlight by giving it 50 volts. It expected 8. There was a bright flash, and then nothing. Silly me.
I needed to replace it, so off to Ebay I trotted. There, I found a triple light (the old one was a double) for a very good price - £2.99. A very good price. Too good to be true! So I bought it.
A couple of days later, I realised that the usual email telling me that it had been dispatched, had not arrived. I waited a couple more days, then checked again, and it was at that point that I noticed that the seller had never sold anything on Ebay before. Uh-oh.
So I emailed the seller. No reply. I waited a couple more days until the last date of arrival had passed, then I raised a case with Ebay.
More nothing happened. A week went by.
So I asked Ebay to take action. Within a few hours, I got a full refund.
And that's why I buy things via Ebay.
So then I bought my light, it cost £5.89 and it arrived from China within a week. I've put a different connector on it, so in future, I won't make the same mistake.
