i'd say no in regards to the question about if they work well. i've read, been told, heard, found out about ... more ocmplaints with this flash kit than the fat errored ak2. so many people are having build issues, where the kit gets stuck in their dsi. they also complain about connection issues, where the kit stops working for no reason and the ds/dsi freezes on bootup. i know a few people who had the spring break as well as the msd slot stop reading the msd. granted many of these people are heavy users. most are homebrew coders, some love to do compatibility testing, etc. also if you run the wrong thing you risk bricking the kit for dsi mode. acekard made it clear they would not release a reflasher to fix any problems.
i think everyone should jump off the wagon... and walk for a while. wait and see what comes out next. wait to see which kit unlocks dsi modes. wait to see what the hackers do. and wait for the price of the thing to drop. $180? you gotta be kidding me -- in this world economy? soccer moms unite and wifi mario kart!!
