I have purchased a total of 5 360s and 4 360 pros. The 369s were slow charging so I replaced them with the 369 pros because they say they are faster charging. None of the 360 pros charge any faster. I can start charging at 80% and the message comes up that I need to use original equipment to charge faster. It says it will take 3 hours and some odd minutes to complete the charge. I am a professor and do a lot of grading courses on my phone and the 360 pros advertise they charge quickly even when playing games. By the time I finish grading while charging, I have lost charging percentage instead of gaining. One of the 3 foot 360 pros has never worked and nobody will help me get it replaced. I have contacted them with three emails and taken their surveys twice but all I get is did you get our response? Check your junk email. I have and have responded twice with no further response from them. I am through with them. They don't work well and they won't stand behind their product or even acknowledge the problem.
