    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. ;-)

    Um poderoso aparelho que testa e mede muitos componentes e ainda identifica semicondutores, e mede valores de ESR muito importante para técnicos e estudantes de eletrónica. Chegou muito rápido e sem qualquer problema no transporte. Aproveitei e testei alguns componentes que tinha em cima da bancada. Veja as fotos. Um grande aparelho por um custo (preço) tão pequeno. E ainda traz uma caixa de acrílico transparente para o gabinete que aloja também a pilha Os meus parabéns á Marca GeeKcreit tem vento muitos módulos e kits muito bons. E como sempre recomendo. Obrigado 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 working. I was a bit scared, becouse read to much about cracked display problem. First, i thought, its scrached badly. But thankfully it was just the screen cover. It's flawless. I got the cover too, but dont wasted time atm to put together that. Megérkezett és működik is. Kicsit be voltam kúpolva, mert rengetegen írtak arról, hogy törött kijelzővel kapták meg. Elsőre frászt kaptam, hogy rommá karcolták, de szerencsére az csak a védőfólia volt, amit eltávolítva megoldódott a probléma :P és így már kifogástalan. Küldték a burkolatot is, de nem pocsékoltam időt az összeszerelésére egyelőre.

    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.
