The product is good, the finish is not terrible, but anyway it is set away from the eyes. For the kneecap against the setting is more than difficult, if not impossible once the projector in place! and if it is not tight enough, the kneecap moves slowly until it is really visible! Clearly, a good product for its price which deserves a more accesible setting the ball but still fulfills its role very well once properly adjusted and tight!
