I ordered 2 of the EVODS from FastTech Sunday, realized Monday I forgot to order extra heads. Ordered some Monday. Emailed them with my order numbers and asked them if they could ship them together. Within 20 minutes I had an answer that that would not be problem. I have not received shipping confirmation yet, but once they ship they usually take about 10 days to get to Florida. For the price, if they work I won't care if they aren't real Kangers. Have not had any problems with anything I have ordered from FT in the past.
