## Description

Bold Smart Lock SX-33 Bluetooth Smart Cylinder Lock - Silver

Review: Empfehlung - Der Einbau und die Einrichtung waren sehr einfach zu machen. Mit dem Auto entry klappt auch, aber nur wenn ich länger weg war. Bei kurzem Briefkasten und wieder zurück geht es nicht. App Steuerung ist auch gut. Alles zusammen empfehlenswert.
Review: Gut - Im Großen und Ganzen bin ich zufrieden. Etwas wackelige Aussendrehknauf. Funktioniert bis jetzt zuverlässig. Nur der Clicker ist zwar gut gedacht aber Qualität ist ungenügend. Schon 2 Stück in innerhalb 2 Monate kaputt gegangen.

### ⭐⭐⭐⭐⭐ Empfehlung
*by S***K on 20 September 2025*

Der Einbau und die Einrichtung waren sehr einfach zu machen. Mit dem Auto entry klappt auch, aber nur wenn ich länger weg war. Bei kurzem Briefkasten und wieder zurück geht es nicht. App Steuerung ist auch gut. Alles zusammen empfehlenswert.

### ⭐⭐⭐⭐⭐ Gut

Im Großen und Ganzen bin ich zufrieden. Etwas wackelige Aussendrehknauf. Funktioniert bis jetzt zuverlässig. Nur der Clicker ist zwar gut gedacht aber Qualität ist ungenügend. Schon 2 Stück in innerhalb 2 Monate kaputt gegangen.

### ⭐⭐⭐⭐⭐ Très bon produit je recommande
*by P***T on 27 August 2022*

Malgré le faite qu’il n’y ai pas de traduction en français et que l’on ne comprend pas bien quelle partie est à l’intérieur ou à l’extérieur c’est un très bon produit pour le moment car il n’y a pas longtemps que je l’ai et qui me satisfait grandement. malgré les problèmes de langue les services Bold sont très efficace merci . Si cela peut servir à quelqu’un voir mes photos
