Review on KAIWEETS Voltage Tester: Non-Contact And Contact Pen For 12V-300V NCV Testing, LCD Display, Live/Null Wire Detection, Buzzer Alarm, And Wire Breakpoint Finder - VT500 by Jeffrey Choudhury

Likes:It uses a standard AAA battery rather than a hard-to-find button battery like my old tester.It has beeps plus has a digital readout of the voltage. My old one just beeped.The screen glows green for low voltage and red for high voltage.This has a LED flashlight, although not real bright its more than my old tester had.You can use this to test the polarity of a battery. It's a plus but I don't see the need to do that too often.This also has a continuity tester. You have to actually touch the wire that you are testing with your bare hand to use this feature, so make sure that its deenergized.Dislikes:If you are lefthanded like me, be prepared to read the screen upside down.It needs a hold button or some other means of retaining the voltage readout for a few seconds. It's nearly impossible to read the voltage unless you are at eye level with the tester. Not an easy task for an old fat guy like me when the outlet is 16" off the floor.
