Some things don't go out of date. Good old fashioned Customer Service is one of them and I feel that Revtronic has stepped up to the mark.
A Mercedes W168 instrument cluster was sent (Special Delivery) for pixel repair and received back to me in suitably protected packaging three working days later.
From the returned condition of the cluster housing it would appear that a high quality of workmanship was employed and the correct tools used to effect the repair.
The display is now back to its pre-fault condition.
Many thanks.
