Having installed multiple windshields on friends GS machines, I decided to purchase and install the Aeroflow windshield on my own new GS. I watched several friends migrate through several different size and type of windshields only to have them eventually get the Aeroflow.
Ordering: Ordering was easy on the Aeroflow website.
http://aeroflowscreens.com The windshield was received in less than one week. The windshield comes in medium, tall and extra tall. The website has enough information to allow selecting the approprite windshield for your use.
Installation: This is one of the easiest products to install. The instructions are wonderful. Inside the complete packaging are six separate smaller packages, each numbered. Each individual package contains all the hardware and instructions necessary for that step. Start with package #1 and work through all them till finished. No parts left over, no questions, simply wonderful.
Opinion: A totally complete package that simply works. I am using the medium size windshield and lower half fairing. Bike is totally stable in all wind conditions. Air flows over my helmet and is smooth all the time. Expensive, but worth every little bit.
