I received mine yesterday and can confirm that this is a genuine Xiaomi Wiha with Wiha branding on the box and Wiha engraving on each of the 24 screwdriver bits. It also has the 2017 RedDot design award packaging.
The price keeps shifting and I had paid $26 delivered for mine with a Kogan First free trial and you could wait till the price is at a more comfortable level for you.
I've been looking for a genuine Wiha for months and have previously returned about 6 orders from various sites including Catch that were advertised as a Wiha but were fakes.
This is for those who have been hunting for the original Wiha and have been disappointed to receive the Mi or the Mijia without the Wiha branding.
There are many listings on Kogan for this product, but I can't confirm those, but this link was a genuine Wiha.
Yes, there are cheaper non-Wiha clones out there.
Thanks to Jimojr for the original listing https://www.ozbargain.com.au/node/626434
$7.99 delivery (to 5115) without Kogan First
