I should be a design engineer. I often find glaring flaws in other great products. This exercise is no exception. a built-in LED that blinds you if you have to look at the tool while using it, which I do most of the time. Designers could easily solve this problem by dragging the light a bit or making a rib around it. The light is very bright and emits in such a way that it can illuminate the whole room, not just the place where you are working. You can use the tool without glare if you hold it a certain way, but if I can stick my head right behind the tool and drill through something (which is the only non-glare orientation), I should be using a regular drill and not angle drill. Unfortunately I had to defeat the light by wrapping it with a rubber band. What a waste. I gave it one star because poor design ruined an otherwise excellent product. 5 Update June 2019: I found a way to make this exercise usable. I took two tiny self-adhesive rubber bumpers and attached one to each side of the light and now the light only shines forward, not to the sides. You can buy bumpers at most major hardware or department stores, or here at Revain. I added photos.
