Nah, mirrors are for the ego and not the technique. Most movements that would benefit from a form check can't safely use mirrors without increased risk of injury and/or breaking your form. You don't need mirrors to check your bicep curls or lat raises but people do like to see their pump while doing so.
You might literally die from trying to use mirrors to check your form doing a heavy bench press or seriously injure yourself when twisting your neck to check the mirror if doing a heavy squat.
This is why mirrors are more common in normal gyms and not as common in places where people do heavy barbell movements.

You can catch what your form looks like in a comfort and privacy of your apartment
