I hate this microwave because of the end of cook time beeper.  It is relentless and obnoxious.  The only option is to have NO signal at the end of the cook time. 
The microwave works great, but the beeping is so irritating that I’ll never buy another one unless you can have a standard one beep finish, or one beep every few minutes.  This thing beeps every ten seconds.  WHO thought this was a good idea?  You’d have to be partially brain dead to need, or want, this.
