Product review (2 stars): SQEEKS!!
SQUEEKS constantly.  Didn't realize it until I moved it to another room where I could hear it.  yikes!  By the time I realized it was such a distraction it was too late to return or exchange!  BUT, it does the job.  It has a 24 hour clock, they don't tell you about and programming it is like trying to read japanese instructions.  But figured that out after a bit.  lovely idea, but it SQEEKS!!!
