Pros: Slim, usb powered, bootable.

Cons: sale didnt last very long should have bought more than one

Overall Review: if this thing drops back to 16.99 or so that it was on sale for i'd definitely buy them. the biggest failure i keep getting with my PC is the optical drives stop functioning i've purchased 4 dvdrw drives and they all stop being able to read. cleaning the lens does not seem to get the job done. This tiny little usb drive is portable and well sealed so i can use it however much i need then unplug and put away for strage so nothing happens to it.

Pros: cheap, retail box.

Cons: Worked only 20 hours then bricked. Opened, charged it to full working great the keept nagging to update android to 4.4.4 so i gave in and said fine do it and get it over with. worked after update about 4 hours then stopped powering on. Never dropped, never scratched or anything in any way.

Overall Review: Google really shouldn't force you to upgrade operating system on devices that are not able to support it.

Pros: its 4k

Cons: - Defective cameras with dirt on lens throws camera out of focus unusable. - Very bad cables - NVR very difficult to use and replay - Hard drive too small for 4k system, Seagate brand is very bad for NVR use and is what you get with this system

Overall Review: If you are planning to go POE be prepared to spend a lot of money this is not cheap. Expect bad quality control and defective cameras 1/4 cameras turned out bad. You will need to upgrade hard drive before even starting the system up. They use Seagate garbage drives that will fail very quickly with bad sectors so this is not for a critical application use.

Pros: has all the features you'd want without going x570

Cons: this board will not run ram at 3600MHz or even 2700MHz. Ram rated at 3600MHz will not post from overclocking profile on the modules. the highest speed you can run ram on this board is 2666MHz anything above crashes and is HIGHLY unstable.

Overall Review: Ryzen 5600x, 64 Trident z 3600MHz, ROG b550-f gaming wifi this combo will not work cant run ram over 2,666Mhz will fail to post at 3500MHz. 2666 to 2800 will post but highly unstable.

Pros: it lights up

Cons: it would not run at more than 2666 MHz at timings listed on the modules. anything above 2700 is unstable and crashes windows. at above 3000 MHz it fails over clock completely and reverts back to 2666 MHz

Overall Review: it lights up the set profile does not boot with ryzen 5600x only runs at 2666 MHz no matter what you do. maual, auto and xmp profile wont boot higher than 2666 MHz stable.

Pros: supposed to have been good at one time or another

Cons: tested voltages by shorting green with ground it spins up tested voltages those check out also but installed in two systems does not power on.
