Very poor customer service and unreliable product. My ear device stopped charging. The charger had to be replaced. No big deal, it happens…. But…. you can't go online to order a replacement, so you have to call, and there …. is no answer. They offer to call back, which means I have to put away my work even if it's inconvenient for me and talk to them when it's convenient for them, not me. It's a very nice service, but definitely not for customers. Perhaps the unreliability of the product and the subsequent replacement fee is part of their business model. I had to spend another $300 on replacement parts.If it still came with adequate assistance and everything was delivered on time, it did not!.They advertise a lot, but don't be deceived into believing they're the only ones that sell these things. I mean that, because there are so many other sellers you may buy from.
