Customer feedback highlights ease of bending, shaping, cutting, and installation, with reports that the tubing works well. The main concern is mixed feedback about softness. That trade-off matters for a line that is intended to be shaped during installation, so consider how much forming and handling your application requires. The aggregate ratings lean strongly toward five-star ratings, but ratings alone do not explain specific experiences.
