    The firmware in this tester is called Mtester version 2.68. But it's a very old one and unknown by the developer, the latest version atm is the fork from Karl-Heinz Kübbeler: TransistorTester 1.13k. I updated the tester with the recommend firmware but there was a problem, because this one use a 16Mhz crystal. Ok, no problem, WinAVR is my friend and i made compiled my own 16Mhz version, sourcecode is available in the www, And now it's a great device, next i replace R1-R6 with 0,1% resistors. ;-)

    A powerful device that tests and measures many components and still identifies semiconductors, and measures very important ESR values for electronic technicians and students. Arrived very fast and without any hassle in shipping. I took advantage of and tested some components I had on top of the countertop. Look at the photos. A big appliance for such a small cost (price). And it still brings a clear acrylic box to the cabinet that also houses the pile. My congratulations to the GeeKcreit Brand have a lot of very good modules and kits wind. And as I always recommend. Thank you Banggood

    Excelente. Funciona de maravilla. Rápido y lo suficientemente preciso. Es posible configurar el contraste del display pulsando 2 segundos el interruptor. También haciendo puente en 1-2-3 se ingresa en modo calibración.

    Je suis très satisfait de la qualité de fabrication et finition du produit. j'ai bien apprécié le boitier découpé au laser qui fait de ce produit un outil robuste. j'ai ajouté une alimentation extérieur débrochable, la pile 9 volts est toujours utilisable.

    Arrived and clear. I was a bit odd, becouse needed to find about cracked beef problem. First, i want, i want scrached. But what happened was just the other day. It's okay. I wanted the money, but dont wasted time atm to put it back that. It's here and it's working. I was a little taped because a lot of people wrote about getting it with a broken display. At first I was scared that it was scratched, but fortunately it was just the protective film that was removed and the problem was solved :P and so it was impeccable. They sent me the casing, but I haven't wasted any time assembling it yet.

    Arrived to UK in 6 days. Packaging not sufficient, 2 plastic bags with no bubble wrap or card insert. Unfortunately the screen was cracked, the unit is still operational but top line of display does not appear. Also, it seems that when designing the PCB layout they decided to attach the screen in only 2 places, which probably didn't help with the poor packaging. My package did not include brass standoffs and fixings as pictured, instead I got longer bolts and plastic spacers. Overall a good value item but shipping process needs to be improved.
