Obviously a copy of the Rapid box, but damn this one's good too. Comparing them reveals differences in build quality: the Fotodiox is slightly thinner and has a heavier plastic construction. But if you want something that works and works well, you'll be very impressed with this guy. I've used it for several photo shoots including a 3 day Indian-American wedding and the results from the softbox are excellent. The great advantage of the device is its portability, ease of installation and disassembly. I was set up and ready in under 2 minutes which is a huge plus for a wedding photographer. This softbox provides excellent lighting for macro photography, portraits and more. I had a 600ex-RT as my light source and had no problem using both the wired and wireless solutions with this device. If you don't love your gear and don't expect 3-5 years from it, I recommend choosing a fast box. However, if you want quality lighting, don't skimp on your gear. I'm sure the build quality of this device will give you a year of worry-free photography. At only $70 for the price of this thing, it can produce bloody amazing results that are worth a year.
