I tested this product and found it cannot reach 120 watt threshold as advertised. The transistor heats up beyond 100c and rapidly drops the output wattage. Continuous use at 100C eventually burns out the power transistor. Heat sink efficiency is not sufficient. A much larger heat sink and cooling fan would help.
