In this paper we investigate the existing limits of explanatory power of UTAUT2 as a source of consumer experiences and customer knowledge structuring. We apply a structured analysis of existing UTAUT2-based research to identify an extended conceptualization of UTAUT2 components in various contexts and with specific contextual add-ons. Based on pilot data collected in 2018 on digital wallets adoption (study 1) and barriers on musical streaming services adoption (study 2) we analyse 2 extended UTAUT2 models with PLS-SEM. The results of the analysis demonstrate consumer tendency to risk aversion (added variable) significance in the context of digital technologies usage, whereas effort expectancy and gender effects (original UTAUT2 variables) turned out insignificant in both studies. The results of the pilot studies preliminary confirm the research idea of UTAUT2 possible contextual limitations.
