I have had the ProjektD on my 09 for about a year and a half. My criteria at the time was that I wanted something larger than the stock, but not huge, I wanted it tinted, and I liked the lip at the top of the shield. The ProjektD fit my list, the price was right, and I was ordering helmet locks and a few other things from them as well. Their shipping can be a little on the pricy side, but it is coming from Asia so I would expect it to be a little more. I will say that both times I have ordered from them, the shipment has arrived MUCH faster than I would have expected considering the origin.
Installation is straightforward, no surprises there. I am not really sure how to rate its performance..... compared to the stock windshield, it is a great improvement. At full down I get the wind in my face and at full up, it get real quiet behind it. I will say that at full up and my height, the lip at the top is right in my field of view and causes distortion. I can lean down just a tad and resolve it so it isn't a big deal to me. Honestly, it has been on there so long I really don't remember what the stock shield was like and I have nothing else to compare it to. If you have any questions that I can answer for you, please ask away...
