I bougth this usb soldering iron as kind of a gimmick and had very low expectations of its ability to solder anything at all. To my surprise it is very powerful, fast and easy to use. It doesn't take up much space and I can use it everywhere in conjunction with a powerbank. Beware thought, it does need a powerbank or usb-charger capable of delivering at least 2 amps for it to work. I wouldn't have thought it but I highly recommend this product and have currently purchased another one - just because :D Cheers!
