I just got AiBs installed a couple weeks ago and so far so good. I do wish they were a bit brighter, but seriously...I'm just happy to be rid of the stock yellow-ness. AiB seems to be a good quality product.
That being said, there appears to be a new product on the market. If I were still looking for angel eyes, I would seriously consider the Bellof LEDs from Japan that WSTO is now selling. PnP solution from a great vendor.
