This digital clock works for the purpose I bought it for. I was able to mount it using the screws rather than the tape because the tape just doesn't work as well. I like that it is easy to remove from the mounting bracket to change the battery. I like that it is illuminated at the touch of a button. The only negative is that it doesn't keep time accurately, but it is close enough to still be of some value.In conclusion, if you need a very percise time keeping clock, this isn't the one for you. If you don't mind having to resent it periodically, then you will like it.
