Once a Siedle product is launched on the market, it has already successfully withstood a tough baptism of fire. 

It has been exposed to a series of gruelling tests under simulated conditions: tropical heat, extreme Siberian cold, and salty sea air. Every button, every housing and every seal is subjected millions of times over to every kind of physical maltreatment before it ever finds its way into a customer's home.

We place the most stringent demands on functional safety, reliability and durability. In almost every instance, Siedle specifications stipulate standards in excess of statutory requirements. But in the unlikely event that something should go wrong: New generations of devices are designed to be reverse compatible, and we still maintain a stock of spare parts for systems which are decades old.
