The electrical tape is just like The Force – it has a dark side and holds the universe together.

The best electrical tape can be used everywhere, properly holds things together, and will not yield to sunlight.

Good insulation properties, resistance to extreme temperatures, and an affordable price – this is what makes a good electrical tape.

A poor-quality electrical tape has a limited range of applications, has no mechanical resistance, and indeed does not hold things together for a long time.
