Pros: Works like a charm - cheap - nice little LCD readout - fast

Cons: no case

Overall Review: You have to plug in the connectors in a certain order for the device to give you a correct reading, otherwise it will incorrectly beep and show the 12v2 is low (LL) and your PG doesn't work. So, 1) plug in the mainboard 20-pin connector on the right side of the tester, with the clip facing up, 2) plug in the P4/P6/P8 connector on the left side of the tester, clip facing up, then, last, 3) plug in the power supply cord via the wall outlet. All the numbers should register, with no beeps, if all is well.
