Has anyone here bought the Meike MK320 flash? The size and price are right, but I have read elsewhere about the usual QC issues from some buyers...DOA, early death, bad TTL exposures, etc. I've read the (poorly translated) manual and it's unclear how deep the TTL support is. Can it be controlled from the camera like my FL360L? I saw no mention of TTL slave mode but will it act as a master to trigger TTL slaves? Anything else you'd care to share about this flash would be appreciated.
