May 27, 2019:

Dynamo Regulators is very pleased to announce that it has agreed to licence all aspects of manufacturing and marketing for the DVR3 & 4 regulators to a Dynamic new Company. The aim is to complete the transfer during July. Unfortunately, due to changed circumstances DRL is unable to accept further orders for the DVR3 & 4 products with immediate effect. Please note that DVR2 availability is not affected by these changes. We are sorry for any inconvenience during the transfer period. Further details will be posted here when these are available.
