I recently sent one of my powerheads to Ecotech for a cord extension. When it came back to me, the insulation was exposed and didn't reach the heat shrink. The insulation inside the heat shrink helps act as somewhat of a strain relief which is highly noticeable when compared to my other powerheads. I'm worried about the cord bending and the wires coming out of the connector or worse one of the wires getting abraded. Should I be concerned or am I over thinking it?
