Effi software has helped us all. The mentality of locksmiths is killing the trade. Pple want everything free and yet make money out of it for a living. Why not pay affordable price to keep development so you stay in business. If everyone bought clone and cheapened the work, soon we all will be out of business and on the streets cos car owners will start doing keys by themselves. Let us support Effi since it is growing alternative for people who cannot afford tango, tmpro, tagkey and original zedbull. Like said earlier, sierra should make easy payment via liberty reserve or show exchanger for webmoney from liberty reserve. since zedbull is registered product, he cannot use paypal without problems for copyright infringement, so we all use alternative method. eFfi has future to be best product since it is not clone. No one supports clone. You have no access to ask for update. Effi is like original idea to make new software for clone hardware. All you who have it have made good money using it, what is wrong to pay????
