Pros: This is the first power tester I've owned so my opinion is somewhat limited. It does have a clear easy to read digital display. Case is made of sturdy aluminum which gives it an edge up on others with a plastic case. It has connections for testing 20 and 24 pin ATX power, also for P4, P6, and P8 connectors. Molex connectors, SATA power connector, and floppy.

Cons: The only complaint I have so far is the poorly written manual, written in broken English. I will have to search some tech sites for proper explanation on how to use all features.

Overall Review: Very satisfied with this purchase. Replaces an old Dell T7400 workstation.
