Quality Memory
Excellent value, reliable brand and great performance. Used now for probably close to 2 years and no issues at all. Always worthwhile buying from an established brand, with a strong reputation. The only problems I've ever had (with a home build PC), is when I've gone for a cheap, no-name brand trying to save a little money. Whatever the saving, it's never worth it, just for the hassle alone. Look for a bargain, but always go for the option with a good company reputation, as with these memory sticks.

Easy to install and works great.
I installed 32GB of this (4 x 8GB sticks) with no fuss and no settings needed changing. The ram seems pretty damn fast which is great considering I am a heavy gamer and software user; I installed this in between rendering an animation in 3DS Max for uni and it fixed my comp crashing from my previous ram which was defected (was a different brand)and crashed under high stress; this ram is great however and has no problems. Also they look sweet as in their case and in my comp. Ordered Monday and arrived by Friday; the seller was very informative and even sent me an automated (well I assume automated) text informing me of the delivery day and if I wanted to change, rearrange the times or have it delivered to a neighbor instead.

Perfect RAM upgade to my ageing gaming PC
To answer some frequently asked question: this is DDR3 RAM, on full size RAM modules. Laptops: It's unlikely to be compatible with laptops, which usually have a smaller form factor RAM modules. (Search 'Laptop RAM DDR3' and it should come up with compatible kits for laptops) Will it work on XYZ motherboard?: DDR3 was the common standard between 2007 and 2014. Motherboards post 2014 are likely to need DDR4 memory, or possibly DDR5 which launched in 2020 If you want to know whether your specific motherboard is compatible with this kit: Google it's model number, or look in the motherboard manual and check it's "memory" spec. If it says DDR3, you're good to go! :) For the review itself: I used this to update my old PC from 8GB to it's maximum 16GB capacity. Helped me meet the suggested specs for Elden Ring, and other modern games. No issues installing the RAM. Clicked straight into place. The Metal heatsink is low profile enough that it didn't obstruct any other components. Instantly recognized in the BIOS. Would recommend to boost an older PC, for gaming or general use.

VALUE!!!
I almost. ALMOST got these babies running at 2400mhz CAS12. They unfortunately don't run stable at these speeds so it isn't an option. I've noticed that others seem to be having the same problem so it's a pretty 'set' thing. They start at 1600mhz, but easily swap to 1866mhz without any modifications. By lowering the CAS by 1 you can hit 2133mhz. To hit 2400mhz, you need to up the voltage to, I think it was 1.8v, which is abnormally high, most other (better) ram is only tested to be capable of running at 1.6v max, so run this at your own risk. Although it may be worth a quick punt to see if your particular brand of RAM is capable of running stable. Don't ever change any other values less you want to fry your Mobo. Considering they're the cheapest sticks of 16GB available, I'd say they're damn good value and well worth a 5 star rating. Also 16GB of RAM coupled with an SSD is just a fantastic combination. The system will run incredibly fast.
