Yes, and I have yet to run into any issues.

A few questions:

1. What are the issues with the broadcom chips I'm hearing about?
2. Will the normal ring size work with my GS4, or do I need the alpha size? My hands aren't very large and would like to avoid the alpha size if possible.
3. I have a larger battery than the stock (ZeroLemon 7000 mAh battery) which does have NFC. Will this help or hurt me with the GS4 sensitivity issue?

Thanks for all the hard work you're doing!
