      Great Iron at least for a little while

      Overall: 3.5 out of 5

      I buy these irons for some of my technicians because they love to "turbo" button. For the price, these irons work well. They do not last anywhere near as long as the Weller irons, but they are cheap. Keep a few in your desk to replace them when they break. Overall a great cheap iron.

      Great idea, but short lived

      Overall: 3 out of 5

      What a clever idea! I used to put a diode and a rocker switch in the power cord of my 40W soldering pencil, back in the day. When I didn't need much heat, I turned the switch off, and the diode effectively cut down to 25W. So here's a pencil with the diode and switch built into it. The switch is a momentary, so you have to hold it down to get the super heat effect. It really does get hot! But as big jim said, it's not really 130W. And, as dx points out, this product does not last long. I've purchased several in the last ten years, because A) it's so handy and B) it only gives a few hours at high heat before it burns out. Replacement element? Faggettaboutit!

      Nice iron but specs are wrong!

      Overall: 3 out of 5

      MCM needs to check the specs on this iron, while it meets the 20 watt spec the boost is only 42 watts not 130 watts. I have 2 and both check the same.
