Buying a laser for your miter saw of any size also includes compound miter saw would be a great idea.
If a project requires precise and clean cuts, laser essentially acts as a guide by shining a beam onto the blade of the material where the blade will cut the material.
The great thing about this feature is that it decreases the risk of error and makes it a safer way to use tools precisely.
Now almost every miter saw comes with a laser guide, after a long time using laser damage therefore you also have to buy new to adjust for great accuracy.
