At $106 / ZAR R1,774 this is entry level DDR4 3600. This kit comes with Micron IC's, which is common of late with many entry level DDR4 kits.
If you're willing to tune the timings, you some good performance to be had, but I'd lean towards the 4133 SKU, doesn't cost much more, but has a more exciting IC by and large for overclocking it seems.
