CatalogueNew parts we supply carry the respective manufacturer's warranty. Every unit is tested in-house before it ships and is delivered with its repair report. Our quality management system is certified to ISO 9001:2015 and audited by DEKRA.
FAQ
From turnaround times to warranty coverage — here are the answers to the most common questions.
With a repair, we restore your unit and then send it back to you. The usual turnaround time is 5 to 15 business days.
With an exchange, we immediately send you a tested replacement unit from our exchange stock. You then send the defective unit back to us.
An exchange is the right choice when every hour of downtime counts.
