I have an Aeroflow on my latest acquisition. I wasn't all that bothered about it because it is quite imposing but having ridden with it now I'm very impressed with the amount of protection it gives. I went for a spin around the local block soon after purchase and was half way round before I realized I'd been riding with my visor up and I didn't have my usual ear plugs in – it was quite amazing and I'd rate it very highly. I still look over the top with ease but the air flow clears my head easily. I'm about 5'10″ and the top of the screen is 18″ from the top of the large light to the top of the screen.
