Inexpensive, but absolutely useful

Was skeptical at first, what can a macro flash for 36, - EUR already suck? But the manufacturer Polaroid is a quite well-known manufacturers for Photo articles of all kinds. So I bought after much research the macro flash. The build quality is absolutely fine. The luminous efficacy, both as a flash, as well as a permanent light is also useful. One has to be aware that both the flash and the continuous light only works on the M-mode of the camera (Nikon D7000 with Micro-Nikkor 40mm). But with a bit of flair and a little trying out the manual settings can be absolutely useful photographic exposures. However, anyone who believes professional recording, to be able to make ala CSI Miami which is wrong in this flash. That should then but invest properly and a manufacturer macro flash, like the Nikon set R1 or R1C1.
