Review on 🎯 Precision Target Bubbly Spirit Mounting by Jesse Stewart

Suitable for level indication. But it won't be useful to give degrees of inclination for the entire 6 degree scale. After two degrees, the bubble quickly jumps to the outer edge and tends to stay there until it's almost flat again. The 49mm diameter base is wider than many, which is a good thing. Without a flange, the actual bubble level is 32mm.
