The CEO of VVKB emailed and asked if he could send me this heater for a bit of a review. I needed a block heater after the dismal performance of my sump heater.
The Titan-P1 heated the engine and didn't burn the Subaru to the ground. Not overly keen on the cheap worm drive hose clamps. I'll swap those out for some Mikalors.
