1. Half of the incoming calls don't ring, transferring calls is near impossible, and after months and months of this bad but necessary experience, it now will not open at all..This app is very unreliable and buggy.
2. It's barely usable and can't be trusted.Works great.
3. Could be so much better if its features worked as advertised.
4. Horribly developed.
5. I have had so many issues with this app.
