The University of Johannesburg is promoting decolonization of knowledge and Industry 4.0 based higher education interventions to prepare locally relevant and internationally competitive students. As regards to that, a project sponsored by teaching innovation fund, and based on development of virtual lab for manufacturing engineering education has been done. This paper reports an analysis of the feedback of students who explored the Industry 4.0 virtual lab developed for manufacturing engineering education. A feedback questionnaire with a total of twenty questions on virtual lab learning management system and its effectiveness was developed and distributed to the students for anonymous feedback. It is found from the analysis of the feedback that 90% of the students were agreed with the quality and effectiveness of the developed virtual lab. Some of the recommendations and qualitative feedback of the students were found very useful for further development of virtual labs.
