Really pleased with the service that Mike has provided. He has refurbished my Clearflow visor battery with NiMH replacements for the old Nicd. He had the patience and time to reconfigure the previously dodgy plug connectors with new. The unit is now once again fully functional, probably better than when I bought the unit 25 years ago. Mike could not have been more helpful and the overall cost involved was very reasonable. Highly recommended.
