Hot garbage & a complete dumpster fire. Worse than useless. Complete and utter waste of time. Skip it. Even if the devices connect, there's no indication of the status. Just a perpetual 'preparing' on one device and 'connecting' on the other - never ending.. full 24 hours both phones connected to chargers... Never ending, no indication of status.. etc.. wasted a day and eventually just used another method that only took an hour. Shame, shame, shame on them!
