have have recent bad experience with travel alarm I go out search for a new one . this one be easy to operate . Buttons easily allow change of setting . it be very lightweight . the cover be make of plastic which make it seem flimsy but it work out ok - that add to the lightness . it be sturdy enough for my daily use . although a travel alarm I use it daily . it be very inexpensive and yet better than many more expensive model that I be retire .
