Great flash with more than ample power and flexibility that is small and light and easy to use.  The LED video light is an added bonus.  Recycle time is quick and it works well as a remote flash off-camera.

The value for this thing is just phenomenal! I can't believe the power of this flash for the price! I've used this flash at several professional shoots, and no one thought anything of it. The diffuser that comes with it is a little cheap, but it does get the job done. Overall this thing packs a lot of punch. and the pivot head really allows you to have it point in about any direction, and change directions quickly.

This is an excellent flash for that situations when you don't need heavier equipment. I unpacked and use inmediatly with outstanding results. You have to be aware of the recharging time not to miss a shot. Great for general use. Nice travelling flash

A great flash. I recently purchased this flash used with the case included for 65%  the retail price (dropped/damage my other one). For my use I could not see advantages to the newer version. Well worth it. Works seamlessly with my 6d,50d and rebel xt. Have used this flash with my canon 50mm,85mm and Sigma 70-200mm zoom with flawless results.

I needed to get more flash than was produced by the stock flash on my Canon EOS Rebel.  I did not want a large, heavy (4 or more batteries), mounted on the camera.
This unit solved the problem!  It only uses 2-AA batteries and makes a big flash for a smaller unit.  I'm a realtor and it fills the room for color rich pictures.
I love the bounce feature and find I'm using it whenever I have a white ceiling in a room.  I'm not a photo artist but this Speedlite in combination with my 10 to 20 wide angle lense has helped me to produce wonderful listing photos.  I love the compliments from the other agents in my office!

This flash was on my wish list for quite while. I received it as it was scheduled - thanks Amazon! - and had just a few hours to get used to it before shooting a very important event: a wedding.

I am very pleased with the outcome. Red eyes were always a problem, but not with this wonderful device.

I tried all modes and all of them yielded very good results. The battery life is a bit short, but taking into account the number of photos I had taken it was quite good.

My overall experience with this product is very positive and I would say that for any serious amateur photographer using Sony F828 (which I like very much too) this flash is highly recommended

This flash works great on my D800. It is powerful, recycles quickly and offers ETTL and high speed sync. I use YN 603 triggers to use it off camera in manual mode and use it in TTL mode on camera. The build is solid. It does not do commander mode master, but can receive commander mode signals. I'm pretty new to flash, but I'd say this flash offers great performance, versatility and value. I have to admit, I have a hard time programming it to get it in the right mode for off camera work, which is greatly simplified by using the YN 603 triggers. My best shots have gotten so much better after getting into flash. This unit is a great entry point.

I reviewed the HVL-F20S flash here: http://www.amazon.com/review/R2KTQXR7KLA7XH/ref=cm_cr_rdp_perm

This is a nice bundle, however. I use the lens brush to keep my stuff dust-free, and and who can't use a spare battery? The battery charges just as quickly as the stock Sony battery and provides just as many shots, with or without flash.

The flash itself is absurdly powerful for its size and the coverage and range are excellent for something so small physically.

I shoot photos as a hobby so i didn't want to buy an expensive flash. this flash is so powerful. Be careful some photos can get washed out. With a little experimentation, you're photos can become amazing!

I was shocked at the quality of this flash after i opened the box. I was expecting substandard merch baaed on the cheap price but this flash feels incredibly well built. Seems like yongnuo has done a great job of listening to thier customers. They have updated this flash with a metal hotshoe in recent months whoch is good because this flash is very heavy. If considering buying this be warned that this is a full manual flash. No TTL or CLS metering, no rear curtain sync, no highspeed synch. But there are work arounds for the sync if you use you on camera flash to trigger these in slave mode then you be able to "unlock" rear curtain and highspeed sync. The yn560 works great as an on camera flash but you must know how to set your power to the correct setting luckily for most it is easy to adjust the power as you go. Where these flashes really come to life is with strobist work. Getting these off camera and on light stands is the best reason to buy these. When doing off camera work you do not want automatic metering because you will loose all control of your exposure.

With that said i have popped off over 1000 shots with the yn560 and have had no problems. I liked it so much that i ordered a 2nd unit and will be ordering a 3rd in a few months.

I didn't really need the power or master ability of the 580EXII, so I opted for this flash instead.  It works great, the TTL is very easy to use and it produces great portraits with bounce flash.  It has plenty of power to work in reasonably sized rooms, but big cathedrals or warehouses may pose a challenge.  I have been reading Neil van Niekerk's Tangents blog on flash photography, and this flash is a good starter unit that allows one to perform much of the interesting on camera flash work that he talks about.

Slight annoyances:  It can't rotate 180 degrees in both directions (180 to the left, only 90 to the right) which leaves a quadrant of inaccessible space for bouncing over your right shoulder.  If I were some sort of pro wedding photographer this would make things more difficult.  The power adjustment in manual flash mode is clunky up and down buttons instead of the quick to use thumb wheel on the 580EXII.  There isn't a good slot to put a bounce card in the flash, as it is taken up by the wide angle diffuser that flips down.  None of these drawbacks are really big enough to drop a star, especially given the nice discount from the higher end units.

I've had this for a couple of days and love it! Its a great point and shoot, provides crisp, clear, beautiful images in auto mode. But, it also allows you an incredible amount of control and versatiltiy with the preset modes and the manual modes. You can get great results with "art-ier" shots that encorporate depth of field, saturation, etc.

I've had great luck shooting in an indoor setting with natural light coming through the windows and lots of flourescent light coming from overhead when I've adjusting the white-point accordingly. It performs well in low-light situations too. I like the programmable function button that gives you a short-cut to the screen that pertains most to the situation you are shooting.

The portability, image quality, add-on lenses, shoe for a speedlight flash, price, and proven Nikon quality, make this a great choice for someone looking for the most versatile small digital camera they can get.

This is a great little speedlite and does a fantastic job as the wireless slave flash for the Canon T3i which was the main purpose I purchased it. The 270X II also makes a great flash attached on the camera to replace the built in flash. The tilt features are great. I was a little skeptical purchasing it because of its size but I am more than pleasantly surprised with its performance.

This flash is fantastic.  In several ways it is better than my 580 EXII.

The first way is obviously price.  Build quality is on par with Canon.  The plastic is a touch more "plasticy" but not enough to raise an eyebrow.  The shoe mount tightening ring is better built than Canon's.

Another way is shear simplicity of menu navigation.  The EXII is an ergonomic nightmare, these full color menus are bright and astonishingly simple.  Setting up a functioning master slave took 5-10 seconds without reviewing any directions - it actually makes sense and all the options are right there and intuitive!  EV adjustment is a snap and clearly displayed.  Major modes are color coded.  It's great.  Canon should copy it wholesale.

My exposures tests in all sorts of conditions were indistinguishable from the 580 EXII, including the flash color.  An Omnibounce style snap-on diffuser is also included (as are the pull out varieties), lowering the price even more.  It appears this is an EXACT copy of Canon's software and hardware in all modes and options, but with a FAR superior GUI.

Did I mention that one can set up a whole studio full of EV calibrated E-TTL slaves for the price of one EXII?  And you'll actually be be able to verify they are all set correctly without spending an hour setting them up and testing.

Don't even think about buying a Canon flash.

I actually had to buy this as a replacement unit due to the mount having recently broken on the first one I bought.  The plastic mount is the Achilles heal of this and many other flash units.  Still trying to get a replacement part!  Otherwise this is a fine if not outstanding flash.  It is actually a bit more advanced that my expertise. The learning curve is pretty steep for me, now that I understand some of the settings and uses, I'm pleased to own it.  Cannot wait to get some replacement mounts, as I'm sure they will break again.
