You need this if you have the X200, especially if you shoot with the strobe head. Fits perfectly and secures very tight to minimize the possibility of damaging your light.
I've thoroughly enjoyed my new lighting set up. The service I've received has been A-1.
Great service great product
Solid. Simple. Inexpensive. Great idea to protect your flash.
Not much to write about. Easy to use, just push in and twist to protect the bare tube on the AD360.
