Wanted a mic to be able to pickup 360 deg at our lecturn. Works great just what we needed.

Good all-around lapel mic

We have dozens of these and the cartridges have always worked fine. These omnis seem a bit more prone to feedback than something like an SM58 so I am trying out a hyper-cardioid cartridge as well to see if that will minimize feedback while still working for the average instructor who wears the mic too far down their shirt and sometimes facing away from their mouth. The new Shure mics as a whole have one fault which is that the battery compartment is too tight and rechargeables are had to get out.
