Not pleased with radio performance

We purchased these radios to use in our care facility for communication purposes and HIPPA compliance. This is the list of issues that my staff have reported: Lots of static, picking up conversations outside of our facility, very hard to hear, some of the ear pieces do not work (staff cannot hear through them) microphones not working, radio volume not working (can barely hear with some of them). Very hit and miss with these radios. Need something more reliable that works consistently.
