Pros: It will tell you if the product is bad

Cons: Not sure of the accuracy of this device.

Overall Review: The tester will tell you if your Power Supply is good or bad, but it is not testing it under load. I tested a 250w supply that passed by the tester determination, but failed under the load used to run a system requiring a 200w supply, and eventually failed completely.

Pros: Easy install

Cons: This board burned up a chip right after owning it a year.

Pros: None

Cons: Read below

Overall Review: Hard drive I purchased in 2019 was manufactured in 2017. Manufacturers warranty was expired before I ever even unwrapped it

Pros: NONE

Cons: Left makes little to no sound

Overall Review: Finally assembled my entire custom build within 34 days of receiving all equipment and the left speaker cannot even be heard at all. The rest of the equipment works

Pros: None

Cons: 4 separate sticks failed completely when installed separately, in pairs, or all together. These were being installed in a Sony Vaio VGC-RB50

Overall Review: Bought these sticks on the quality behind Corsairs name only to be disappointed in the outcome.

Pros: Does it's job as programmed, good quality material as to be expected

Cons: Every system I have put this on (6 different ones now) it has put a severe drag on the rest of the system using the memeo software. No matter what the specs on the machine were. I had one client out of 6 not complain, he elected to not use memeo at all right from the start and back up when and what he wanted

Overall Review: Might explore a different option for any other externals I am requested to install.
