S. ansu.Nagata 3 October 2017, 03:15 I have Mark 7, claritymeter and virtual claritymeter. The cost performance and technology of THETA - METER is No. 1. The meter is a great invention of the century, I thought that it was a blend of science and spiritualism. I think that Mikhail Fedorov-san made a really wonderful meter. I expect that THETA - METER will be popular in Japan. Thank you very much. Add a comment ansu.nagata 11 October 2017, 17:50 Thank you for answering my question many times.
