The Gear has 65 teeth 

Symptoms of Fault:  This is a common problem where the electric roof fails.  
If you can hear the motor turning and it’s not releasing the top cover, it’s likely the teeth have stripped. 
The company uses poor quality and the teeth strip on them overtime. 
However our gear is made in Aluminium and It won't fail. 

(Aluminium is not an ordinary material)

Aluminium is a very light and strong metal. 
This is one of the main reasons why aluminium is being used in so many different transportation industries.
Aluminium is also corrosion resistant.
