According to my experience, this soldering tip is a total waste of money .The tip is flimsy and breaks easily which makes it unsuitable for industrial and scientific applications. The performance is very POOR and inconsistent. The product lacks durability and quality, and the replacement tips are expensive. The only good thing about this is that it is easy to assemble and use. But overall, I would not recommend this product to anyone looking for a reliable and long-lasting soldering tip..
