I have been using the Jingda Leather iron for a couple weeks now and I would not want to give it up. Thanks to Lyn for discovering it. With the relatively simple modification of filing the foot flatter it becomes an indispensible tool. I particularly like the uplifted tip that provides accurate work in tight corners, and allows one to approach the edge of a piece of fabric with good control.
I cannot measure the temperature with my infrared thermometer, due to the reflectivity, but using a digital oven thermometer, it appears to have very little temperature swing, probably due to the digital thermostat. It will get hot! And the thermostat dial has to be taped down. If you have a file, and are willing to rework a new tool, I can recommend it!
I am using it in standard US 110/120 volt current. (Mine came with a simple plug adaptor, which you can also buy one online for the Chinese “W” style plug.) It does not take a converter/transformer to use, just a simple plug adaptor.
Now, if I only had the courage to take a file and round the tip of my model aircraft iron so it isn’t totally flat . . . .
