I tried out my MT07S and found out that mine has some quality issues:
- The reflector has two minor imperfections, not really a problem but ugly somehow

- The dome of my XHP70.2 has a scratch on it


- The side switch blinks blue even with almost fully charged (4.09V) protected Imalent 18650 cells. According to the manual it should not start to blink before the capacity is down to 50 percent.
