      A well made tool for small electronics that are difficult with a traditional soldering iron- especially for repair.

      Overall: 5 out of 5

      I bought this specifically to repair a USB plug for my tablet. The wires were poorly attached and broke off the lugs. The paces are too small to be able to work with an iron, but these were focal enough in their heating to do the trick. I only wish that other tips were available for the for other special purpose soldering/desoldering. I may make my own or alter the provided tips if need be.

      Don't Expect Performance

      Overall: 1.5 out of 5

      A handy idea poorly executed, but at least they are cheap when on sale - worth $20, at least.. Potentially capable of easing removal of surface mount components and caps at both leads at the same time without having to "rock" them, but only moderately effective at doing so due to tip size limiting access. Poor quality control, evidently. One review above says too hot, mine was not hot enough. The tips are too thick and misalign easily. I had to regrind them by hand to make them more usable. Forget about using the larger ones - the iron is not hot enough in at least mine to be able to power that much surface, and the edges align too poorly. Then it burned out altogether. Using a cheap dimmer as above a good idea for the too hot ones as a cheap solution. A variac can be used for ones like mine that are not hot enough since most can boost voltage a few Volts a bit to 130V when you need a short burst of heat/ and lowered while idiling to control temp or extend life, but I didn't hit on that until it was already failing, which it would have sped up anyway had I done that and left the V set at max. Definitely do set up some way to control temperature during idling at least to extend life. So it's handy but don't expect long life or ease of use without having to fix it up first and frequently realign the tips/clean/ then regrind after to maintain it. Mine didn't last long enough to burn out any tips as in the review above.

      We've been using one of these to remove surface-mounts capacitors in many types of equipment repairs, especially flat panel TVs and it has been working great for us. It makes the job of removing the caps without damaging the PCB so much easier than using a standard iron and having to rock the capacitor back and forth until it is lifted from the board. This is definitely a worthy tool for any modern workbench.

      Cheap. Hot. Barely Usable.

      Overall: 1.5 out of 5

      Using a blowtorch to light birthday candles... This describes this tweezer-type iron. It's far too hot for even RoHS-compliant soldering temperatures. The description says "soldering/desoldering tool" yet the packaging simply says "desoldering". You cannot solder an SMD resistor with this iron without damaging the circuit board traces. It works fine if all you want to do is fling a resistor or other 2 lead component off its pads. I'll be building a light-dimmer temperature controller...I suggest you do the same. The tips are quite thick making operation difficult. You can't really tweeze the component without crashing into the board. The tips are also quick to burn up; they heavily oxidize in minutes further causing difficulty. My advice? Well, it's cheap so if you need to remove a bunch of wrongly placed resistors - it's good in a pinch. If you need to do some soldering, use an iron.
