Summary: I recieved it from Walmart in a very short time. It works perfect. I bought a more expensive brand from Amazon and it was not working. Fllash givesyou very nice lighting specially if you aim it at the ceiling. Battery last long. It is a little smaller than competition which is good. TTL works good with my Nikon D90. Power adjustment and other settings work great. Just remember to set the speed of camera to 250 or less. Not too much less.
Summary: you get what you pay for. its cheap plastic, need to be mindfully of the battery door. doubt if it could survive a drop. i use energizer rechargeables which tend to heat up in the flash, so its something to keep an eye on. it is a good flash to learn flash photography. i ve had it for 7 months and its performed well. ive used it off camera as a slave with triggers, didnt have a problem there.
Summary: I bought this flash as a slave unit, but it works better than I thought. The slave mode I use as a fill flash, and it's 5 power settings are excellent at reducing lite out put, and lag time is unnoticeable. when camera flash & slave fire, and with no cable connecting the two. When mounted on my Nikon D3200, the motorized zoom head worked great and accurate, the flip down diffuser&reflector are handy. The Flash focus assist was V. good.
Summary: All functions basically work as they should. My only issue so far is that it will over expose my subject randomly. but if I set up exactly the same way again, it's perfect. Works well with my Nikon D40-X.
