a small price for a very good technical side and flash performance. quick in reloading delay, fixed by a click on the SLR. Swivel head 360 degrees and remains solid when the inclinements. no beep beep but triggering the flash when the flash is ready / loaded. HSS 1/8000 perfect for outdoor / cons day. everything is there. However, ATTENTION: we can put an external battery, but only PIXEL. Godox the propac are not compatible, regardless of the same canon cord. ATTENTION: delivery times are extremely long (allow 1 month) and the packaging very damaged. Would recommend for budget travelers.
