Title: microsyncdigital hotshoe contact problems
Review: I tested these units at a group shoot and had multiple problems with the unit inconsistently maintaining contact with the camera's hotshoe. I tried 3 different models of Canon bodies. Another photographer tried them on his Nikon bodies and had the same problem. The owner of the units said he has the same problem and used gaffer's tape to reduce the problem. Even with the gaffer tape, failure was about 25% of the time. By adjusting how I held my camera and placing my thumb on the unit providing preasure to maintain the contact, the unit functioned normally about 85% of the time. We had ten different photographers use the unit and all had the same problem.
