Small but powerful sled flash, read this review carefully before buying it: PRO: - simple and intuitive flash, very small but with high power, I appreciate that there are not too many keys; the package includes a bag to contain it, a power cable and a stretched plastic speaker. CONS: - the power cable is still USB-A USB-C, I will never stop expecting a double C output; - the plastic speaker is very rigid, I had a hard time applying it to the flash until I found the solution: you have to push the short side on the respective short side of the flash and, by pushing, the diffuser will adapt to the flash; as shown in the attached photo, the latter is not one of the best speakers on the market: it significantly lowers the power of the flash and the blurring of the shadows is minimal. CONCLUSION: The flash is very powerful, on the instruction booklet it is recommended not to use it close to the eyes (obviously), but the flash is also often used for portraits: for this reason I recommend buying a better speaker than the one supplied, possibly in silicone, so as to be able to better weaken the power of the flash (by doing the tests at due distance, the flash (with the diffuser applied) has practically stunned me). With the help of Patrick Stella, you can see the difference between photos with or without a diffuser, practically minimal: the first, brighter with sharp shadows (without diffuser); the second darker, slightly smoother shadows (with diffuser). Good flash in terms of ease of use and power, small and portable. I'm giving 4 stars for these missing precautions.
