The clock is great, however to mount you screw into wall in several areas. How to you change the batteries when needed without having to completely remove the clock.

I like the clock, but I didn’t realize there were no numbers at all on the clock.

Ridiculous to hang and change the battery

Nice clock but what a b#tch to put up! Do you think the mounting holes could be at a 90 degree angle, maybe at the 12 o'clock and 3 o'clock points? No, that would be too easy for installation. Make them at uneven points around the circles so that it's impossible to judge where to make the holes in the wall. For the large size, a stencil would have been helpful.

After trying multiple batteries, the clock still never worked. Also, I don’t understand how you’re supposed to change the battery when it dies because the clock literally gets screwed to the wall. No good.
