Bought 3 of the Geeni Prisma Strip 2M. Initially it wouldn't even connect to our wifi, but after some digging, found that it wpuld only connect to our 2.4ghz connection. No problem, fixed. New problem, when trying to sync with the light strips, it reads "fail to connect" once it gets about 3/4 the way. So now I have 3 light strips that are essentially useless. Am willing to change it if a solution can be found, but I have yet to find one anywhere.
