Awful. It won't even connect my literal brand new from the box, Charge5. Literally, every other bluetooth compatible device will connect to my Android but this device won't and no one can give me an answer as to why on their so called help and support team, which only speaks halfway decent English, and/or talks like they're trying to sell me something. I don't want you to sell me anything, speak like a normal human being and help me connect this device to my phone. 🙄🤦‍♂️
