Additionally, the kit includes a 13-piece accessory set, catering to diverse soldering needs.

On the downside, while the product is robust with its 100% metal fuel tank and safety features like an ignition stopper, it does require butane fuel, which is not included. This might be an inconvenience for some users who will need to purchase fuel separately. It's also worth noting that the size and weight of the tool could be a consideration for those seeking something extremely portable. Despite these minor drawbacks, the LEXIVON Butane Soldering Iron stands out for its performance and versatility, making it a solid investment for anyone involved in soldering tasks, especially if you appreciate the freedom of a cordless design.
