Experienced users of similar products know that it is nothing apparent that they really work... Many "no-name" products available for significantly lower prices in all computer shops all over the world suffer by non-stable behavior due to questionnable quality of chips, drivers and manufacturing. Some applications do not accept limited features of many low cost USB to RS232 converters (e.g. implementation of only some of control signals).

UCAB232i is based on integrated circuits and drivers developed in the United Kingdom with professional support and large customer and project base. UCAB232i is designed, manufactured and production tested in Europe.
