It is easy to attach and detach, there is also a sense of hold and it's alright. It seems that there are some waterproofing functions from the rain in the case of putting in the screen, I think that reflection is also taken into consideration and enough. It is a product that was fully considered to be worn on a motorcycle.
It installed in YZF-R1 (07). Installation was completed in a few minutes. It can be fixed by tightening the bolt, but after fixing it will turn if you put in force. I use the iPhone 4S in a case but do not rotate while driving. The thing I bought was disappointing because there was a scratch on the clear part.
When I was looking for a navi case for Jupiter's YERA 506 Si, I bought it because the size of this product is just fit. Handle clamps, straps, rain covers were also included and were satisfactory products.
