Solid quality — very happy
Great little Simplecom DA330 — setup was easy and it works perfectly.
Really pleased with this
Honestly one of the easiest online purchases I have made. Ordered in the evening and had a tracking number by morning. Delivered to Canberra in 3 business days. Product is well made and does exactly what we needed. My partner is happy with it too. Highly recommend.

Good quality and arrived ahead of schedule. Very happy.
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.
