Pros: A nice LCD that displays useful information about the PSU being tested.

Cons: None that I know about.

Overall Review: Whenever I dont test a PSU it comes back to bite me in the end. Now I test any new PSU for confidence. The next time I am debugging a flakey system I hope I remember to test the PSU first. If you are running a serious studio / workplace that uses computers that you are maintaining, you need this, or something like this, in your toolkit.

Pros: Easily-read display, not merely a black-and-silver LCD image, but black-against-bright blue for clarity.

1-- Precisely cut, solid connectors for all standard cables, never too tight or too loose

2-- Sturdy metal case, slim and pocket-size

3-- Safe working range violation-- beep alarm indicates when voltage falls below a safe/acceptable minimum or exceeds a safe/acceptable maximum specific to a connector (from -+5% to -+8%, depending on connector), which is a tremendous aid to identify an intermittently failing PSU circuit, but without need to stand over the unit tested, meter in hand, waiting for the event.

4-- Abnormal voltage detection-- display indicates when voltage falls below a connector-specific low minimum or exceeds a connector-specific high maximum, and flashes "LL" or "HH" on that abnormal voltage

5-- Display indicates "PowerGood" (PG) status in milliseconds, with alarm if the PG value falls below or exceeds the range of 100 to 900ms

Meter is ideal for routine checks of test and reserve/spare PSUs, to prevent damage before connecting valuable equipment and possibly damaging disk data. Without this meter, the only status indication is the wryly-labled "smoke test", which indicates possible equipment damage

Cons: None, with Possible confusion (to new users) on the difference between the alarm for violation of safe working range and a flashing indicator for abnormal voltage. To a new user, the two may seem the same, but

1-- the safe working range violation beep alarm occurs as a failing PSU value briefly enters a damaging range one or more times in a running, real-time test for random events

2-- the abnormal voltage display flashes after any single event, indicating definite damage/malfunction in the PSU

Overall Review: This product reviewed by "Definitely Ambivalent", a purchaser and satisfied user (after one week)

Pros: Works as it should

Cons: None

Overall Review: Handy tool to have.

Pros: Good device.

Cons: No latch indicator on 20/24 pin connector.

Overall Review: The supplied printed instructions were O.K., but viewing the PST-3 YouTube videos made a big difference in understanding the various PST-3 connectors and the LCD display.

The 20/24 pin connector does not indicate which is the latch side. Can be confusing the first time inserting a 20-pin connector.

Accidentally bounced the PST-3 off a hard tile floor and it survived with no damage.

Pros: Simple

Cons: Limited instructions, YouTube was helpful.

Pros: Good readouts

Cons: n/a

Pros: Works Very Well, Digital Readout ,Easy to Use. Excellent Price.

Cons: None

Pros: It's quite accurate and simple to use, I didn't want to jump my PSU to make sure it was functional. It does what it was meant to do. Its compact and simple design makes it easy to use. Takes the guess work of what the voltage you are getting from your power sources.

Cons: None

Overall Review: Simple to use and worth getting, never know what could go wrong when jumping your PSU.
