Got my diffuser and rear lip spoiler yesterday through FEDEX exactly 7 days after sending. Beautifully packaged and they included an iphone 4 case as well to compensate for the delayed shipping.
I am very pleased. Packaging was good and the quality is ok for the price. The mesh is perfect but there were two small blemishes on the carbon fibre diffuser. Took me literally 10min to remove the stock diffuser and install this one. The fit is not perfect (one hole does not line up and the ends do not clip in nicely) but again I cannot complain for the price that was paid. Once the diffuser was installed the blemishes on the carbon fibre became invisible. It looks perfect to me. I am super happy.
The lip spoiler installation will be interesting I think because the ends do curl up a bit.
