RadioPopper PX-NP PX Transmitter Nikon Hot Shoe Pop-Up Flash adaptor (Black)

Works great, but keep in mind that if you use this with a PX transmitter that you ALSO use on top of a commander flash (requiring velcro under the PX unit) the velcro makes for a tight fit on this adapter. It works, but the larger clip (rear of adapter) is slightly offset, so it's holding the transmitter a bit more by tension than "hooking" onto the top of the unit. Initial tests moving around the studio appears that it won't fall off the adapter. The clip doesn't appear to stress to the point of breaking/weakening... but only time will tell.In event situation, will most likely use with commander flash (SB-800/900, etc).

Great product, great price, fast shipping, pro packaging. A+++++
