How important is the green dot rubber cover feature for you? - Crimson Trace CT-RAD Micro Reflex Green Dot Sights

My first Green Dot Sight. I like it better than the Red Dot Sight I previously had by Crimson Trace. The 1 detail thing I like about CT Red Dot over the Green Dot CT is that the Red Dot cover is made of plastic and fits snug over the Sight when not in use, to save the life of the battery. The Green Dot cover made of rubber doesn't fit snug, and it will fall off easy. If you're not worry about the flimsy cover for the CT-RAD Micro Reflex Green Dot Sight, then it's a good buy.
