2sec intermittently humming sounds: I will keep this unit a little while longer to see if this unit will hold up) , LED doesn't turn off on 9V batteries neither

when they are all drained the microphone sounds like it exploded and it scares the crap out out of me.

Leaked a weird goo after a year first time, LCD screen cam unglued after falling off the desk once, makes an annoying sound while charging,

We replaced our fire alarm batteries with these and o haven’t had any issues

Thank u

I was using a cheap D rechargeable battery and after a week they started to leak.

Great for larger batteries (C, D, 9V) but it can only charge 4 at a time

a NiMH Rayovac (3000mAh) or Energizer (2500mAh) which are both fake D cells and should be illegal.
