High-tech products arouse ambivalent attitudes among consumers. Such products, apart from their benefits, are also linked with multidimensional consumer risk. The percep-tion of technological risk has greater impact on consumer market choices than the opportunities offered by such risky products. For this reason, part of the research devoted to consumer behavior towards technological innovations focuses on perceived risk. The purpose of this article is to identify the various dimensions of technological risk perceived by consumers. Technological risk has been shown to differ significantly from consumer risk associated with other types of products. The analysis allows one to specify the dimensions of risk perceived by consumers which are significant from the point of view of their choices. These include functional risk, related to concerns about trouble-free operation, risks regarding the ability to handle an innovative product, as well as the product compliance with current industry standards and the availability of complementary products (risk related to the network effect). There is also a risk of losing private data, financial risk and a risk to consumer safety.
