    Not a Bad Flash for the Price

    I bought three of these as open box deals. All three arrived in perfect working order. The manual is clearly a poorly translated to English little book that can be hard to decipher at times, but if you are familiar with speedlites, or watch a Youtube video on it, these work great.

    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!

    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!

    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.

    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!

    NOT FOR HIGH-END CAMERAS

    Overall, this product performs as intended: It provides an external flash for a camera at an affordable price. However, when I attached it to my EOS R5 I noticed a lot of issues that had it lagging behind. Firstly: It uses a visible range finder. For the most part this isn't a problem unless you're taking portrait photos and you're shining red cross hatch lasers in your subjects eyes. Then when I tried using the rapid fire function I saw that the 1/250 repeated flash was inaccurate after the first shot. The flash would go off, but the photos show that the flash is too slow to keep up with continuous shooting. Does it perform at lesser work loads? Yes. Can it handle the advertised universal task? NO. If you just need a flash for rare occasions, this is okay. If you are wanting very technical photography this doesn't cut it.
