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
Deta quality is always reliable and this was no exception. Fast delivery too.

Perfect gift — loved it
Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.
Arrived well packed
The DETA 16A is a solid buy. I was a bit unsure about the size from the photos but it is perfect in person. Delivery was faster than expected. Very satisfied with this purchase.
