I agree with an asterisk indicating this soldering iron is mislabeled and does not produce 200 or 300 watts of power. My digital wattmeter shows 146 watts at low power and 189 watts at high power. And as far as I know, the trigger switch is wired in reverse: full trigger should give more force, but it's wired so a half trigger position gives more force and a full trigger position gives less force. Energy. Both lamps 222 operate normally. Nevertheless, it is an efficient soldering iron even with less power. Only 2 stars instead of 5 for "ease of use" due to the inverted trigger switch, but for only $48 it's still 4 stars for "value". Otherwise well made, hence 3 stars for the overall rating.
