Have 8 pieces of it and am fully satisfied. Gladly again. What they do not have is the zone system of competitors, but they cost a fraction. Only criticism: In tough outdoor use (Running with tripod arm) solve the Funkis often run out because the contacts are not bombs are firmly anchored with the flash. At 100m were the well 20 trips. Simply turn off while running ;-) A Verschlusystem like the Canon EX2 flashes might be better than an increase!
