i really like everything about this but if lowering the clock light setting an obnoxious ringing starts so we have to leave it on the highest setting. i would love a replacement but every other review says there is something else wrong with it so i don't want to bother sending the whole thing back to get one with a worse issue. could at least be issued a discount since, but the company refuses. pretty ridiculous. will probably never shop at homedics again but like this unit aside from this obvious flaw.
