Is that the Neoflash product? Neoflash is terrible.... They don't give updates, usually poor compatibility, and so on. I've never really ever heard of anything positive about Neoflash products....
EDIT: Yes, it is the Neoflash product... Neoflash is considered one of the worst brand in Flashkarts, so don't buy anything off of them, with the exception of DSTT. MK4 is absolutely terrible, and has less popularity than DS-X.
