FX-8801 Replacement Soldering Iron Kit，Adjustable Temperature Welding Tools,for HAKKO FX-888D FX-888 and FX-889 Soldering Station 26V 65W, Electronic Repair, PCB Soldering

I find this replacement works but doesn’t seem to heat as much as te settings I used before. It’s functional, and light weight.

I'm using this iron with my FX-888D. It works fine except the temperature was about 120C different than the original iron. It heated in quickly and drew the same amount of power initially as the original (~120W). Handle is comfortable, with a good rubber sleeve. Cord is is as flexible as the original and is definitely silicone and didn't melt when I held hot iron on it. Tip is properly grounded. It seems durably-made. Plugging in and installing a tip was just as easy as on original. I had to set temperature about 120C lower with this iron than original, to melt the same solder using the same tip. The thermistor reads at 38 ohms vs 55 on original at room temperature, which may account for the difference in temperature readout. I did some measurements in comparison to the original. Heater diameter was 3.7mm, a little narrower than 3.9mm for original. Heater had nearly the same cold resistance (3.36 ohms vs 3.48 original). Thermistor differed somewhat, Ground pin to tip was 0.2 ohms, like original. Included conical tip's inside diameter was 4.4mm, vs 4.0mm for standard tips. Not a big deal since I use others.
