this sound machine\/duel alarm clock be a very good product and work as describe . I be afraid that the display would be too bright , but it have setting to dim it down that make it better . the unit itself be a lot smaller than expect , which be not bad . use the control be fairly easy after a few use , because the unit be very lite you may have to use two hand to make change . the 20 different sound loop be very good , and long enough not to be too noticeable when they begin again . the alarm clock work well and never have fail to wake I up yet . overall this be a good product especially for the price . I would recommend this product to anyone look for a good sound machine alarm clock .
