This flash is interesting and offers four light modes... a video mode (constant light), full ring, or half ring. It does not offer E-TTL or TTL metering. It is a fully manual flash. The power can be adjusted by a couple of stops. Adjusting up and down is easy, as is switching between the modes. As expected, I did see a 1 stop difference in output when I only lit up half of the lights. i also saw a reduction in light output with the colored filters on the flash. there was a slight decrease in output with the frosted cover as well. That was all expected.

Color balance with with either of the diffusers was neutral. The other ring covers give either a tungsten balanced light or a blue light. I did not measure the color temperature, but the raw LEDs appear to be close to a 5000K daylight balance, putting the amber ring at perhaps a 3200K light and I'm guessing about a 6500K light output with the blue ring. I don't see myself using those a lot, but I could be wrong... they are in the bag.

Another nice touch in the bag is a WIDE selection of adapter rings. I am only carrying the two largest (72mm and 77mm) as they are the only ones I would use, but there were rings included down to 48mm. It should be easy to adapt to almost any SLR or DSLR camera and lens combo up to a 77mm filter ring size. It also includes a stand for the flash, but I have not checked operation with a remote trigger.

Keep in mind, this is a $50 flash including international shipping. My expectations were that it would be fairly low power, and it isn't a powerhouse, but as a ring flash, the vast majority of usage would be close-up photography. Power isn't a problem at these ranges. It is kind of plasticy feeling, but the build quality of this unit was pretty good. The ring covers all fit well, but I will be adding indexing marks to make them quicker to switch out. Overall, I think that this is a great value for anyone needing to shoot macro with a ring flash. It is fully manual, so a shooter will need to learn how to set up their camera and adjust exposure, but at this price it is hard to go wrong.

I didn't set up much, just set some batteries in front of a gray card. With the flash power set WAY down, but the flash was only about 6" from the subject. Exposure was 1/125th at f11 or f16 and ISO 6400 on a Canon 24-105 f4 lens with a Canon 80D body(I actually didn't look at the settings on the camera until I was done... I just backed down the power until it looked ok on the camera;s screen). I received the flash free in order to give it a review.

I have used with this item Pentax K3 II and Sigma 17-50mm f/2.8 (all shots taken at 50mm)

I've never used a flash ring before and didn't want to spend a lot on something I don't know if I'll use. For the price, I thought it was worth trying.

Pros:
Cheap and seems to work well enough. Color temperature seems to be fine and lighting is even. I still think this is worth the money as a first ring flash.

Cons:
At 50mm, the flash creates a vignette on the image. The more power you use on the flash, the worse it is. This is only a con because I intended to use my 17-50mm with this lens. I'm sure it would be fine with a longer
