Have had it 3 months or so it is not as loud as some have written but it certainly cannot be used after everyone else is asleep . the buttons are VERY touchy, unplug it BEFORE you take your cup off .I accidentally hit the pulse with my wrist when pushing it back and my finger was at the mechanism that spins the blades took a good chunk of nail off and it hurt for a week or so pretty bruised under the nail bed too . over all a good product for the cost .
