Excerpt: For the price these are going for this is a very powerful flash unit. The head has full swivel capabilities and the flash comes with a handy stand and a swanky velvet storage bag. The controls on the back can be a bit confusing at times without an LCD screen and the instruction manual is a bit vague...
Pros: powerful, swivel head, fast refresh rate,
Cons: no lcd on back, settings are a bit confusing, non-PTTL
Excerpt: This flash gives a lot of power (38 meters GN at ISO 100 & 35mm) for little money. It has some nice features, besides swivel, like: zoom, full manual control down to 1/128th power in 1/8 ev increments, built in bounce card and wide angle thingy.
Pros: affordable, zoom, swivel, 1/8 ev increments down to 1/128th
Cons: stiff pilot button, squeeky tilt, reliability
Excerpt: I own two of these, make for a great off camera flashes. Plenty of power, with good batteries you can get fairly fast recycle time (faster if you buy the external power pack). Build is quite good, although I wish there was weatherproofing (ah well, one can dream).
