My Pros and Cons
Pros: Receiver contained in unit, battery is connected to unit, battery seems to last a long time, battery seems to charge quickly, digital display, different flash modes, lighter weight than my x series, a lot of control using hub and phone/tablet, different strobe modes.
Cons: Seems less durable than x series, you can use plugin on x series units, control wheel is wonky and makes it hard to select menu, needs to be connected to hub and controlled from phone or tablet for full control (wish it was all controlled together like cyber commander), units loose contact regularly from hub, no improvement on distance a strobe can connect to the hub/cyber commander, umbrella mount is annoying (wish it was like x series), mounting hardware is thinner and cheaper than past models, modeling lamp is almost useless. I do wish that your receivers and transmitters had better connection over longer distances and through solid objects. I am forced to use a competitors receivers and transmitters at times.

Superior product. Usual Paul Buff stuff.
Like all the Paul Buff stuff I have bought in the past this light is terrific. It delivers just as advertised. I should have bought two at the sale price.
The manual left out a few details, but one call and all questions were answered.

Good light. Needs moore battery capacity.
I like the flash unit. It took a little time to work with it. But after figuring out how it works I realy liked the capability of the light. Wish you could make a battery with moore capability for this light. That would put this light over the top.
