Pros
I don't know. They place a huge ad in front of the program that is there literally half the time, blocking the entire program!
Cons
OK, is it just me, or is this the dumbest thing you've ever seen? You start the program, and 20 seconds later you get a popup that blocks the program's window. The popup has a timer that counts down for 20 seconds, then disappears. BUT! 20 seconds later, it's back. It seems to do this for the entire time the program runs! So you have to try and do something useful within these 20 second spurts. <p> <p>Stay away! This is the dumbest thing I've seen in the adware arena. The person that thought this up is an idiot! I'm not going to fight the developer to try and use this POS.
Summary

Developer’s Description

By Asymmetric Software

Perform low-level hardware access to identify and control PC components.

Tool that provides services to DLLs to access the PC system hardware. Includes a collection of DLLs performing low-level hardware access to identify and control PC components via I/O, linear address space and CPU registers. Scans the PC hardware directly, bypassing the O/S and provide real-time H/W info. Current libraries include ACPI with AML Source decoder, PCI configuration space browser and PCI tests, SMBIOS browser and structure type validation, Multiprocessor table decoder, BIOS legacy tables decoder, APIC/PIC information, CMOS bank decoder, CPU MSR registers editor, Physical memory and file Disassembler, Windows process viewer, I/O editor with script processing, Physical Memory editor with script processing. Watches to probe Ports, Physical memory, MSR registers, ACPI I/O objects, CMOS registers, PCI registers. Timing Checks for Ports and Memory. CPU tests for MMX, FPU, General instructions and memory access. PCI tests for SERR#, PERR#, floating bus failures and error logging.
