Honest at the price offered. No installation problems. I installed it on a Lenovo motherboard. Unfortunately, the second slot of the motherboard was defective.

I got them for an upgrade on my 9-year-old PC with a "back then gaming setup". Upon initial installation, the computer wouldn't boot. Later on, I realized that I had manually set the voltage on the original RAM sticks higher for overclocking, and the BIOS acted protectively, preventing the startup. I removed them, entered the BIOS, set the voltage to auto on all sockets, and the startup proceeded normally. They have been working great for over 2 months now.

I bought the first set and one stick happened to not work. I sent them for replacement and they sent me new ones. Now it works, but sometimes it crashes. No overclocking or anything. Unacceptable. With 3 different other kits, the system works fine.

Very simple basic RAM.
I have paired it with a Corsair Vengeance X 2666 CL15 on an MSI MAG X570 Tomahawk and Ryzen 5600X.
I ran a 12-hour memtest without any errors.
No BSOD or instability in bandwidth.
Not the fastest, but the definition of cheap and functional.
