What really irked me was that Neptune wouldn’t just sell and send the part. They want the DDR shipped back to CA for diagnosis and repair. When the V2 optical sensors came out, I asked again if they would make the new V2 optical sensor set ups for DDRs available for sale to V1 owners... crickets.

V2 optical sensors - upgrade kit available for DDR dosing reservoirs?
Looks like Neptune is finally addressing the well known issues with their problem plagued V1 optical sensors with the recent release of the new V2 optical sensors. My question is, will an upgrade kit with the V2 optical sensors be available for the DDR dosing reservoirs?
