    Takes some care to assemble but works well once constructed. Check your components carefully before beginning was given some 8.2k resistors instead of 82k. The range of detection is rather limited and the assembled item .shows IR detection on initial power-up. Otherwise fine except it would be nice to have the relay available to switch the mains directly.

    I enjoyed putting this kit together. Of course, I couldn't read the instructions as they were in Chinese but the PCB was marked pretty clearly. Reading some of the other product reviews indicated to me that the clear LED was for TX while the IR LED was for RX and so were soldered that way. I'm not 100 percent I put the kit together correctly as I haven't tested it yet but do have high confidence that it will work. This kit was missing one 1K resistor which was annoying but wasn't an issue as I have a selection of resistors I could pull from.

    all of the bits were there and correct. it was very easy to assemble. limited range but works well. value for money.

    Pacco ricevuto dopo circa 30 giorni, in buone condizioni generali. Il circuito viene consegnato in Kit da montare. Montato risulta funzionante. Ho avuto delle piccole difficoltà con il circuito stampato in quanto le traccie in rame ed i fori sono molto fragili, quindi da montare non molta attenzione i due (2) diodi Tx ed RX tendono a staccare le piste in rame.

    Recibidos todos los componentes, PCB de buena calidad. Funciona correctamente. Las instrucciones sólo en Chino, pero la PCB viene bien serigrafiada y no presenta dificultades su montaje. Por si a alguien le es de utilidad, el diodo blanco es el D2 (Tx) y el negro el D1 (Rx). La resistencia variable sirve para ajustar el tiempo que se mantiene cerrado el relé, de 0 a 40 segundos aproximadamente. Totalmente recomendable.

    Assembly was easy. The only problem encountered was that two 8.2K resistors were supplied instead of 82K ones as required. Fortunately, I had these 82K resistors so I used them instead. The range is about 10 cm or so but it works well.

    I built up this kit for one of the guys in my model train club so he cold use it for a track trip to run his crossing flashers on his model railroad. He loved it!!
