I was a bit concerned after seeing some negative reviews. but i had no problems and found the iron strong enough. If you're used to weak 30 or 40 watt irons, be careful with this huge 100 watt iron; It's slightly larger so it can be uncomfortable and it might be easier to overheat the component. but I plugged it in, did a quick can and started soldering. No problem. It could become my new favorite (electric) iron.
