Review on ALLOSUN EM4610A Black Tester Troubleshooting by Omar Svagera

I bought mine on Black Friday on a dollar off so only $11 and a great deal! I found it very useful as it detects square wave pulse levels etc. It's a really handy tool that I can use to determine if IC pins are outputting signals correctly, etc., and also for general short circuiting and troubleshooting. This is one of those tools that, as soon as you have it, you wonder why you never bought it before. Here is great value!
