Does what it says. As with this this type of device it is important to have it mounted so that heat can dissipate. The higher the amperage the hotter the device.

The helper is super handy, especially if you work with medium size PCB boards as it allows to hold the board steady in every position. It feels pretty sturdy and of good quality.
