  • Good product, bad service
Works as advertised. Horrible customer service with it being a Chinese distributor unfortunately. I had a charging issue with one of two I have in a bank, and they just wouldn’t respond to resolve the issue. Thankfully Amazon backed me with the A-Z guarantee and I was able to get a refund to get a replacement. Just communicate with your customers! Thank you Amazon ... show more
