### ⭐⭐⭐ erst ok - dann defekt
*by S***L on 11 December 2025*

UPDATE: 3 Jahre hat der Tauchsieder gehalten, also über die Garantie, jetzt ist er defekt/kaputt! Somit teure Reperatur. Nur für den Hobby-Einsatz. Habe den Tauchsieder jetz seid 2 Jahren im Dauer-Einsatz zur Warmwasser-Aufheizung im Einsatz. Ohne Probleme

### ⭐⭐⭐ Abdichtung
*by F***K on 2 November 2025*

O-Ring wird beim einschrauben herausgedrückt! N

### ⭐⭐⭐⭐ Generell ein tolles Teil, aber…
*by S***N on 13 December 2021*

Ich habe mir den Heizstab für meinen Campingbus gekauft um auch unterwegs warmes Wasser zu haben. Grundsätzlich funktioniert der Heizstab einwandfrei, beim genaueren Hinsehen fallen jedoch ein paar Sachen auf. - Der Temperaturbereich ist etwas ungenau zu regeln, die Einstellung ist auf etwa +-5grad genau. Für das Campen gerade noch ok, ist halt ein Unterschied ob man 37grad heisses Wasser oder 32grad warmes Wasser beim Duschen hat. - Es wäre schön gewesen, wenn man eine Schraubmutter für das Gewinde des Heizstabes dabei gehabt hätte. Der Heizstab ist grundsätzlich konzipiert damit er in einem Metalltank mit vorhandenem Gewinde eingeschraubt wird, die simple Funktion, Wasser warm zu machen ist jedoch auch in anderen Behältnissen gefragt. - Einen EIN/AUS Schalter hätte man am Heizstab schon noch unterbringen können Alles in allem jedoch ein tolles Produkt, ich würde es trotzdem empfehlen!
