my wife want a dual alarm clock with a red display because red be suppose to be less disruptive to sleep . the good : very large , clear , bright , red display the radio have surprisingly good reception and sound very good when listen to news . I have not try listen to music but it be probably a little lack in bass response . the user interface be about as intuitive as it could be give its large number of feature and the manual be also good . large project time . on a surface 6 foot away , the number be 10 '' high battery backup allow the alarm to wake you even if the power be off the bad : this clock be not a `` atomic '' clock that receive very accurate time signal from government transmitter . it be simply preset to the correct time at the factory and be run on its battery backup when you get it so you might have to fine tune the time anyway . this also mean that , the next time congress change when daylight saving time be , which last change in 2007 , this clock 's automatic setting of daylight savings time will be wrong . fortunately , this feature can be turn off . the two brightness setting only change the display on the clock and not the project time . there be very little perceive difference between the two brightness setting and I think both be too bright for nighttime use . I think the project time be a little too bright and this be not adjustable and in some orientation of the projector you get a slightly distracting glare of the project light off the lens at the top of the projector . although you can focus the project time , my clock can not get all the number in sharp focus at the same time . this be a bit annoying but the projector be still very usable . the backup battery be cr2450 which cost over $ 7 dollar at Radio Shack and about $ 5 from Amazon . you can get they cheaper through Amazon from third party but I always wonder if those be counterfeit . the battery should last for year if the clock be keep plug in so this be not a huge issue . I wish they have use a pair of aa 's instead . although the project time can be rotate 180 degree , it can not be rotate 90 degree so if the clock be on a night stand at the side of you bed and the main display be face you , number project on the ceiling be 90 degree off from where you would like they . the unusual : I buy this clock after read the review that it be too bright . I figure , be a electrical engineer , I could modify the clock and either make the dim setting dimmer or add a light sensor that adjust the brightness base on room light . I be , with the addition of 6 part that can be find at Radio Shack , able the change the dim setting into a automatic setting that dim the clock nicely when the room be dark . the brightness of the dim setting could also have be change by change the value of a single component . the modification fall into the category of do not try this at home unless you know what you be do . I could not find a clock that already have this feature even though I have a clock from 1980 that do . I could not get into the projector to dim that so I just color the lens with a sharpie to make it dimmer . have take the clock apart , I would say it be reasonably well make and it even have a adjustment for the accuracy of the backup time so it may be reasonably accurate when leave unplugged . overall , I would recommend this clock if you do not mind the bright display .
