S**.
cheap enough to buy and keep waitingfor future uses. proved my big cpu local store lied.
Multiple ports for different testing. Bought mine to test a known dead power supply. Funny was the big local pc store just said they did a complete test blah blah on yet again a failed component. Long story short on big local - 5 items purchase and 5 items returned as failed - brand new. hd lasted 15 minutes and data recovery store confirmed doa. Got this to test and funny the customer was right and again a return and buy elsewhere. One them tools I have in arsenal that is there for when you need it even if used only once.

Fácil y Confiable lectura
Me encanta usar mi probador, apenas llevo un mes con él y parece fiable la lectura. Los materiales son como lo esperaba (por el precio) y es muy fácil de usar. Lo recomiendo para trabajo ligero.

Good, but -5V not supported
Standard easy-to-use and understand tester. Includes test of -12V of older power supplies. I'll be keeping it for convenience and the -12V. FALSE ADVERTISING The description says it supports tests for "+12V, -12V, +5V, -5V, +3.3V, and 5VSB" BUT, it does not test -5V. There is no room for that indicator on the screen. The description of the screen at the bottom even excludes -5V in the list of indicators. This device must have evolved away from the old -5V standard, but the description was never corrected.
