[This review was collected as part of a promotion.] Because it’s a know brand; my old one was several years old. Still worked; but timer was kinda off; some reason had trouble finding refills. Ended up getting another phillips(they are better priced); same thing with the timer. One is going about 15 second the others do theirs on time. I never got my coupons it said would be emailed for the replacements. I recommend; just look for replacements first
