UACC-OM-QSFP28-PSM4 - Ubiquiti 100G PSM4 Single-Mode Optical Module

We are just not quite the same as many of the other online stores.  I know it is easy to say that, but we just aren't.

The Tech Geeks, under their parent company Twelve Times (Worldwide) Pty Ltd trade in Australia, New Zealand and the United Kingdom.

This allows us to purchase stock from suppliers from locations where they have it available.    We are then able to import those products directly, along with providing localised Warranty and Replacement as required.

We only list items that we know have been, or are about to be released to us and since we purchase only in small batches these are often flown in on short time frames.

We list on each product our expected shipments and ones that we have already sent out to customers.   Please use these dates as a guideline as we always suggest 14-21 days just to allow for air freight or customs hold ups.
