I just received my new cyber syncs in the mail a couple of days ago. I am very impressed with the quality of these compared to my old pocket wizard plus II transceivers. They are very well built and seem to function flawlessly so far. I will do a test shoot with them tomorrow night to test them with my 430 speedlites. I sold 2 pocket wizards to purchase 2 receivers and 2 transmitters and had $10 left over. Pretty sweet deal!
