Dortron Showtec Co

Does anyone have any experience with the China manufacture Dortron Showtec Co?

They have some LEDs I am interested in purchasing; its their smaller Flat Round Par lights range from $120-135 each (the larger pars run about $215-270) before shipping and taxes.

FYI: I have had good luck with my Daiseya PAR575-136-RGBAW for the past 3 years.
