I believe that ResearchMinds is the first survey business that I have dealt with that has been prompt and very efficient to encourage and also rectify mistakes. I have only done part of a survey and couldn't and wouldn't go further either as the statements didn't fit my thought. I emailed that I couldn't get through. Straight away Mike emailed apologizing and asking would I except a "promotional pen". I said yes. I received it today, it is the best free pen yet. SO I believe the ResearchMinds team to be trustworthy, striving for excellence and wish them well. Have not had any other surveys from ResearchMinds so cannot comment in regard to these.
