Chinese solder and soldering irons

having problems with Chinese soldering irons and solder. buyer beware. there are many manufacturers in China that makes similar-looking products. the best Sandra most reliable soldering iron is found I got from harbor freight and it's made by Chicago electric. that uses a solid copper tip which is tin plated and a 30 watt element and they last for a long time. the new batch of Chinese soldering irons have 60 watts and have an adjustment dial.
