Issues with flash working properly
585142
There's no way to keep the flash turned on and auto-flash doesn't sense darkness well enough. It's useless at night.

I purchased this flash after reading the other positive reviews here.  My camera is a Canon EOS Rebel T3i which I purchased at the same time (along with UV filter, camera case, second Canon lense, etc.)  After spending all the money that I did to completely update my personal camera system (gave my old Konica Minolta Dimage A2 to my nephew as a gift) which came to around $1789 the flash was the only major camera component I purchased that was not Canon manufactured.  Sorry, but EVERY flash picture I have taken was over-exposed.  I am assuming this is a flash problem and not a camera problem (the camera takes GREAT pictures with built-in flash and non-flash pictures.  This camera also takes great full HD video) I am returning the flash unit today.  Assuming I will experience no refund difficulties with AMAZON, I plan to purchase a Canon flash product which will probably run me another $100 dollars over the cost of this one (I still need to check prices on Amazon).

The Canon EOS Rebel T3i is the latest camera in this category from Canon and has only been out a few months at most and still can be hard to find.  While the website says it will work with the Canon EOS Rebel T3i, I was wondering if the newness of my camera meant they couldn't really test it properly with my camera?  I know the Canon EOS Rebel T3i shares most of the same attributes of the Canon EOS Rebel T2i and I cannot imagine that this flash shouldn't work - but in my case, it definitely did not work.  I am an advanced amateur photographer and I am saying EVERY picture was over-exposed with this flash, not just one picture here and there.

Anyway, of course it is possible that my flash unit was defective and this is not a problem across the board, but anyone who orders online understands the frustration when you do get something that does not work the way it is expected.

Last note --- I will commend AMAZON and their return policies.  AMAZON does take the sting out of ordering online and buying something that turns out to be defective/unsuitable.  Also, I assume where I live helps, but I always get my AMAZON orders timely and swiftly and usually in a few days.

I went ahead and posted many of my pictures that I took with this flash (or else they would not be a lot of pictures on my personal website showing the Easter holiday) that I took yesterday, Easter Sunday.  I am not joking when I say it would be easy for anyone viewing my images to pick out the pictures I took with this flash.  Since I don't know if AMAZON allows links to outside webpages, I won't post the link, but I could give it to anyone who wanted to see what I was talking about if there was a way to do that!

So, thumbs down on this flash (for me); thumbs up to AMAZON for their return policies: and hopefully I will be ordering a Canon flash in the next few days.

Did not seem to tighten very well to the camera. This could be an adjustment issue on my part. The Flash is very nice

i turned on the camera and tried all the different parts, the most important part for me was the extra flash because it is a big factor in my work, but when i tried to turn on the extra flash it didn't work, and i was very upset.

not fit well into the flash. I have to force it. This  product should improve the dimensions.

Works pretty well in adobe flash and toon boom, also I like how it just plugs in and works perfectly without and driver issues or installs. I am satisfied with my purchase as it was a pretty good deal and I required a new graphics tablet. Also it got shipped to me quickly.

Great flash when it worked. Suddenly quit working. Camera would show the flash sign with a yellow spot flashing but would not take picture with the flash extended. The original flash that came with the camera works without any problems. There may be a design flaw as others report the same problem. Flash was never dropped. Attached camera works fine.
Five stars for function ( when it did work) but durability is suspect...

I shoot at times with five flashes.  A lot to keep track of but it will do several more.  Works every time except when I made a mistake.  OOPS

Overall product is good, the only problem come when you try to take photo with flash on, light get reflect at one corner and made photo brighter on one corner.

Have to say unless I'm using this incorrectly I try using the flash on top of it and it doesn't work along with my camera so I could be working maybe just my knowledge how it's supposed to work

Hello I haven't had this flash very long and it's malfunctioning. It's making a weird sound when I turn it on and doesn't flash when it's supposed to. I would appreciate a new one or a refund thank you

The return window closed on this item before I had an opportunity to utilize it in my camera.  Everything seemed to work fine until I tried to download the several hundred pictures I had taken.  The first 38 photos downloaded as they should.  Then I received a message that the flash could not be read, and there were no additional photos on the flash.  Funny thing, when reinserted in the camera, the camera  indicated that there was about 3/5ths capacity remaining, meaning that the camera felt the flash did have photos stored  I took the flash to a local computer company who used a retrieval program and secured 127 photos of Japan Airlines (JAL).  None of them were mine, never been to an airport with this camera.  All of my photos were lost.  The kicker, the existing photos could not be deleted.  I went to a second company, same results, none of my photos and the JAL photos cannot be deleted.  I am out  the cost of the flash plus $50 to have two companies work on the flash.  Plus, I still have to buy a flash for my camera.  Guess who I won't be buying from.

As other reviews have stated this flash failed on me.  This is after I backed up data for a project and then it died.  It is cheap also, it doesn't even lock when open so you have to insert it with pressure so it doesn't close as you put it into the USB slot.

Mixed review for these. The price is right for me as a wedding photographer. If they get knocked over or break I am not out hundreds of dollars. BUT- every wedding season we tend to go through 2 broken flashes. The door that holds the batteries in slightly pulls away and the flash will not turn on. You either duck tape them shut or they are of no use.
We haven't had the overheating issue at events, but it sucks when your flash just won't come on.

I own this camera for 3 years now and I found that this camera has some real cool features. Photos are really good. The only problem with the camera is flash. If you ask somebody to take the photos, you have to particularly tell them not to put their fingure on the flash. Orelse, flash does not popup. Also, you cannot take pictures continously on flash because it takes some time for recharge. This is annoying me allot and I'm thinking of buying a Nikon camera because of this damn flash thing.

Unfortunately the flash did not work after I tested it, even with 2 different changes of batteries.
Am awaiting a replacement from the company.
I used the lens for a Real Estate shoot, and it worked as expected.

Flash does not work as advertised.  It will not work wirelessly. I contacted the seller for help, but never heard back from them.
