    It does what it says it does! Battery life isn't that great so bring extra batteries! The flash takes a bit to recharge in between shots.

    Really nice flash, I picked one up because I have a Canon 6D and it doesn't have a flash. I had a wedding to shoot so I bought it for the price. Works well, a little tricky to get use to versus other flashes I've tried. You will need to buy a separate trigger if you plan to do off camera shooting. Great still for hobbyist to intermediate and will save you money!

    WOAH! Okay, I had a flash previously. It busted on the day I had a shoot. I had to go to a super quick solution and picked this up. I am both impressed and amazed with the quality for the price! If you’re just starting out, this is a fantastic product!

    The flash is easy to set up and great for beginners. Sometimes it can't keep up the amount of shots I want to take but for the price, it does pretty much everything I need.

    Would 100% recommend this for getting great images in direct sunlight along with the ability to adjust the power for low light conditions as well. Just make sure you take the time to learn how to use the flash and practice!

    You get what you pay for. First time flash buyer for my mirrorless Nikon. Took a bit of practicing for the settings but if you know about flash controls should not be an issue. On the heavier side.

    Super VALUE! Feature set like $480 strobe for $60

    I have a Nikon kit. My strobe is a Nikon SB-910 which cost me around $480. I wanted to do multi flash Portrait Lighting, but I was not going to spend $1000 for two more Nikon strobes. I saw this Sunpak-DF4000U by accident and studied the packaging. It was selling for $59.99 but claimed to do everything my SB-910 did. I didn’t believe it, but I bought two of them to see what would happen. They worked with my 910. My 910 was the master and the two 4000 were slaves. Using TTL, the exposure was spot on. The 4000 came with a protective pouch, flash defuser, and tripod adapter/ stand. I also bought the light stands, umbrella, umbrella/strobe shoe holder and Panasonic eneloop black rechargeable batteries from Best Buy. The whole setup worked perfectly. It says it can do the same with a Canon kit, I can not confirm or deny that. The only small complaint is that the Nikon plastic is a bit higher grade than the plastic in the Sunpack-DF4000U. However, for a $420 savings on each strobe I’m not worried about it at all.

    It will probably get the job done

    The quality of the bulbs themselves is great, and we all know that’s what we are paying for...but it might be all one is paying for here. The flash itself is flimsy and unstable, and does not actually work as an off-camera flash for certain camera body models that it advertises as compatible. However, it’s a lot of bulb power, and for $70 dollars and 4 AA batteries, it’s not a bad exchange. I would recommend that this is the flash you purchase when you’re out of town on a gig and your flash breaks. Or because your flash breaks on a job and there is always a Best Buy somewhere and they will usually have this option. It’s out the door for under $100. Just remember that you get what you pay for... and it’s a flash out the door. It will probably get you through, but it’s not going to serve a serious purpose, and you certainly aren’t presenting this one as a great gear gift. However... having lived through the days of a good off camera flash costing closer to a thousand dollars out the door... it’s really quite cool to see such affordable options popping up now, and this would be a great flash for a precarious situation where you need reliable light power but might still break the gear. Like backpacking. Or... cliff jumping. Surfing. Boating. Kids. Home remodels. Just don’t try to take it to work with you, you’ll be apologizing and explaining with some regularity.

    Excellent off brand external flash that works with our Nikon 5600. Th build is solid and flash is worth every penny. My wife loves this flash and uses it for stylized shoots, weddings and senior portraits.

    Bang for your bucks. This may not be the most powerful, but for most events, portraits, and quick easy use... it's great. I needed a flash for a photobooth I did and didn't have money for a big strobe. This does what I need, and with the right accessories is just as effective as a 600$ flash.
