I've purchased several different types, but Shield is the easiest to see and reduces eye fatigue. Coating comes off easily in some cases, but if you ask the manufacturer, they can replace it. If it's flaking under normal use, you should tell me right away. Products that are properly coated will not peel off at all. It has been used for 4 years without peeling off after washing with neutral detergent and wiping with Plexus. I always use CleanInno Beta to clean the car before I ride it. If it doesn't come off after a while of normal use, CleanInno Beta is a real Recommendation. In the case of weak Coating, when it rains a bit in about two weeks. In such a case, it is an immediate replacement, because it may have been peeled off while playing with Shield. Other than that, it's good because it's easy to see and beautifully coated. Even in Clear silver, if you don't stop, you can't see the face much. [Color] Smoke doesn't make it impossible to run at night, but it's tiring, and I'd better not do it with Semi-smoke. I usually run at night on Gold's Semi-smoke and it runs unimpeded. My eyesight is 1.2.
