Neewer Q-S TTL Wireless Flash Trigger(Transmitter and Receiver), Compatible with Sony 1/8000s HSS 5 Group Buttons 8 Customizable Functions for QPRO Q3 Z1 NW420 NW655 NW665 S101-300W PRO/400W PRO

This control unit is good and works well with my Neewer 655 speedlites. Once you get used to it and play a while it’s easy to use but can be a bit daunting. My main issue with it is that Neewer don’t have a universal control unit to use with all flashes. This doesn’t work with all their speedlites nor the vision 5 that I also own so I cannot use all my lights in one studio setup. Missed a trick really.

I recently got the Neewer 'Q3' 200W flash but needed this trigger to allow me to use it wirelessly and I'm very pleased with the results.Note: This trigger does require two AA batteries which are not included.It does come with an instruction manual but as it's similar to other triggers, I managed to navigate around it without any issue, in fact, I found this trigger to be even easier than others I've used in the past.Adjusting settings on the 'Q3' through this trigger is a breeze and the two devices communicate simultaneously and without error within my use, so really pleased.I've used this trigger on a Sony A7M3 and A6600 without issues. Would highly recommend.
