Great Product, When it Works, Terrible Customer Service

I've had my Lymow One Plus for two months now. It worked amazingly well for all of three weeks, and has been a brick ever since. I have sent daily emails to customer support, only to have them respond when I threaten to go to my credit card company to get a refund. They have been telling me for two weeks they would send me a replacement, but I have yet to receive a shipping notice. They actually asked me to give them $500 MORE in advance of shipping me a replacement unit. I'm really hoping they get their ish together, as I was very impressed with its performance the first 3 weeks. Lymow, if you're reading this - do better!
