I've been on a few times, but not online. I have two controllers, both broken. One is really bad, whenever I turn hard right, the mushroom gets stuck. The other one isn't so bad, it just sticks a little, but it is still bad enough to cause me to crash now and then. Plus it makes a horrid squeaky noise when I turn right
I bought a replacement off of Amazon, as I had some vouchers, but what was billed as a genuine Sony controller turned out to be a Chinese knock-off. It looked the business, but you could tell straight away that it didn't feel like a genuine one. The buttons didn't work properly and the vibrating thing was horrid. The biggest giveaway was that the product number that was on the controller was different to the one on the box it was delivered in. Again, all very convincing if you just glanced at it, but a closer look proved it to be a fake.
I'll take myself off into town today and see if I can buy one over the counter. It's my wedding anniversary today (3 years!!), so I'll probably not be on tonight
