Ordered a strobe (YS-D1) and tray package (Ultralight setup for compact), video light (Archon 11V), and spare battery (for the Archon) on 8/1/14. Had an excellent experience.
Was a little apprehensive, but read SB first and it looked like people were having legit experiences.
I went ahead and emailed divervision before ordering to ask a few questions. Sandy, replied within 20m (at 9PM CDT), and perfectly answered all of my detailed questions about how various pieces work and fit together.
The only hitch was that my shipment got stuck with DHL, because it contained a battery. They took it back to divervision, who supplied the necessary paperwork, and from that point it went from being in Taipei at 20:08 (2 hours after I emailed about the lack of DHL tracking updates) to passing through Cincinnati customs at 10AM the next morning, to being at my door in TX the next afternoon.
Everything arrived in new, genuine condition. Obviously, electronics are going to be import models, but if you are cool with what would be considered "gray" market in the US, this is a great place to save some money. Customer service is excellent, pricing is great, and shipping is fast, from my experience.
One thing to watch is pricing on certain items though. I noticed they weren't any cheaper on Ultralight (which is US-made), but I basically got the YS-D1 and complete Ultralight tray/arm package for the cost of the light alone from a US retailer.
