The soldering tweezers do the job well. Though, I noticed 2 issues in the design: 1. Meter scale is highly inaccurate. Temperatures are as much as 50C away from the scale value. The "CAL." adjuster only allows minor correction. 2. The difference in temperature between the tweezer tips was measured at about 30C. There appears no way to correct for that. Despite the design issues, it does get the job done. If you need precision temperature adjustment, you will need to look elsewhere.
