Vou escrever em PT para os BR: O produto é excelente, atende muito bem ao que se propõe e é compacto. Tem como ser montado em acrílico e ainda existe a possibilidade de utiliza-lo com uma bateria de Li-Ion de 3.7V (através de uma placa especifica). Fácil montagem e boa qualidade dos materiais/componentes que o acompanham além da facilidade de uso que é bem semelhante a alguns osciloscópios de ponta. O único contra que eu menciono é referente aos resistores de precisão de 1/8w que não tem como identificar pelas cores, mas isso é apenas um mísero detalhe que é facilmente resolvido com o auxilio de um multímetro.

I have to agree with Brian Phillips. The kit is easy to assemble as the main I.C. is already soldered. The only thing to watch for is that the SMD resistors are listed on the auxiliary sheet and not on the assembly instructions. The kit went together easily and it worked as advertised without any problems. The bandwidth is limited so be aware of that when considering your diagnostic needs. The kit is quite a bargain and provides a couple of hours of kit building enjoyment.

A full kit all parts in package. Requires careful assembly (Some surface mount components). Main IC is pre soldered (as very fine joints etc.). Requires about two hours assembly time. After assembly and testing you have a very worthwhile quality instrument that in my experience functions perfectly as intended. Full assembly and operator information is provided. Note: do take notice of checking the resistor values with an ohmmeter, before assembly as the small resistors colour codes are not easy to read. excellent value.
