Using this temperature adjustable soldering tool has been a breeze. Our team has had no problems at all with overheating or burning the electronic parts we've been working with .The autosleep feature is also a major plus making it safer to use and less prone to accidents. The design is ergonomic and comfortable to hold, making a longer work time much easier. The only con is that the price is a bit higher than other soldering tools on the market. However, it`s a great investment for anyone working in the industrial and scientific fields..
