Customer Reviews
Brilliant Aussie deal
Been buying Simplecom gear for years and this is one of their better ones. The SIMPLECOM DA330 quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
No complaints at all
Exactly as described. Quick shipping. Would buy again.
Works perfectly out of the box
Was exactly what I needed for the price I paid. Arrived well packaged and was easy to set up straight away. Already recommended it to a friend who is also thinking of getting one.
Worth every cent
Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
Does the job well
Simplecom quality is always reliable and this was no exception. Fast delivery too.
Already bought a second one
Placed the order in the evening and got a shipping notification the next morning. Arrived 2 days later in great condition. Product is well made and does everything it should. Really happy with the whole experience.
