Works with PCI, but hands the system using ISA.
Works when inserted in a PCI slot, but hangs 4 different systems using the ISA slot.

Terrible ewaste
Fried itself immediately, started smoking in my PC.

Cheap, avoid.
Used this one time on a motherboard to troubleshoot and everything functioned normally: got codes to check, and the diagnostic lights lit up. Plugged it in to subsequent motherboards and everything on the card has since quit working. No diagnostic lights, no codes, nothing.

If you have something in the adjoining slot, it's useless
It may very well be a nice card with the optional external interface, but this one doesn't have it. So if there is a video card in an adjoining slot (and no other slot in my case) you can't read it or press the button.
