## Customer Reviews

### ⭐⭐⭐⭐⭐ Works as described
*by D***C on May 31, 2024*

Made my job a lot easier. Good quality part with a easy to read gauge

### ⭐⭐⭐⭐⭐ 1234YF system leak adapter
*by D***D on May 27, 2024*

The price and availability was perfect and works perfectly

### ⭐⭐⭐ Funktioniert, aber mit Abstrichen
*by B***2 on September 27, 2025*

Der Lecktestadapter tut grundsätzlich, was er soll, und lässt sich mit etwas Geduld anschließen. Die Verarbeitung ist in Ordnung, aber nicht überragend – vor allem die Dichtungen könnten hochwertiger sein. Für gelegentliche Einsätze reicht es aus, doch für den professionellen Dauereinsatz würde ich mir mehr Präzision und Stabilität wünschen. Insgesamt solide, aber kein Top-Produkt – daher 3 Sterne.
