## Before you buy

- The manufacturer says soldering tips are consumables and does not sell replacements separately. It recommends searching for model C210, but compatibility is not confirmed here.
- The listing’s claimed 8-second heat-up does not establish that the iron maintains heat under load. Customer feedback is mixed on heat retention and battery life, so consider this for short repair jobs rather than sustained work.
- The listing gives a 180°C–450°C adjustment range, a separate 450 Degrees Celsius upper rating and a 350°C default start-up. These are not contradictory, but confirm the desired settings and operating behaviour before buying. The explicit contents list names three tips, solder paste, solder wire rolls, a Type-C cable, stand and case. Accessories are not itemised in the title, so check the selected listing if any particular item is essential.
